Command line tool to manage email domains/accounts/aliases
vmm subcommand [argument ...]
vmm (a virtual mail manager) is the easy to use command line tool for administrators and postmasters to manage (alias) domains, accounts, aliases and relocated users. It allows you to simply and quickly administer your mail server.
It's designed for Dovecot and Postfix with a PostgreSQL backend.
Each subcommand has both a long and a short form. The short form is shown enclosed in parentheses. Both forms are case sensitive.
Most of the subcommands take one or more arguments.
address
The complete e-mail address (local-part@fqdn) of an user account, alias address or relocated user.
destination
Is either an e-mail address when used with ALIAS SUBCOMMANDS. Or a fqdn when used with ALIASDOMAIN SUBCOMMANDS.
fqdn
The fully qualified domain name - without the trailing dot - of a domain or alias domain.
messages
An integer value which specifies a quota limit in number of messages. 0 (zero) means unlimited - no quota limit for the number of messages.
option
is the name of a configuration option, prefixed with the section name and a dot. For example: misc.transport
All configuration options are described in vmm.cfg(5).
service
The name of a service, commonly used with Dovecot. Supported services are: imap, pop3, sieve and smtp.
storage
Specifies a quota limit in bytes. One of the following prefixes can be appended to the integer value: b (bytes), k (kilobytes), M (megabytes) or G (gigabytes). 0 (zero) means unlimited - no quota limit in bytes.
transport
A transport for Postfix, written as: transport: or transport:.IRnexthop. See transport(5) for more details.
vmm configget option
This subcommand is used to display the actual value of the given configuration option.
Example:
vmm configget misc.crypt_sha512_rounds misc.crypt_sha512_rounds = 5000
vmm getuser uid
If only the uid is available, for example from process list, the subcommand getuser will show the user's address.
Example:
vmm getuser 79876
Account information
-------------------
UID............: 79876
GID............: 70704
Address........: [email protected]
vmm help [subcommand]
Prints a list of available subcommands with a short description to stdout. When a subcommand was given, help for that subcommand will be displayed. After this vmm exits.
vmm listdomains [pattern]
This subcommand lists all available domains. All domain names will be prefixed either with `[+]', if the domain is a primary domain, or with `[-]', if it is an alias domain name. The output can be limited with an optional pattern.
To perform a wild card search, the % character can be used at the start and/or the end of the pattern.
Example:
vmm listdomains %example%
Matching domains
----------------
[+] example.com
[-] e.g.example.com
[-] example.name
[+] example.net
[+] example.org
vmm listaddresses [pattern]
This command lists all defined addresses. Addresses belonging to alias-domains are prefixed with a '-', addresses of regular domains with a '+'. Additionally, the letters 'u', 'a', and 'r' indicate the type of each address: user, alias and relocated respectively. The output can be limited with an optional pattern.
To perform a wild card search, the % character can be used at the start and/or the end of the pattern.
Example:
vmm listaddresses example.com vmm listaddresses %master@%
vmm listaliases [pattern]
This command lists all defined aliases. Aliases belonging to alias-domains are prefixed with a '-', addresses of regular domains with a '+'. The output can be limited with an optional pattern.
To perform a wild card search, the % character can be used at the start and/or the end of the pattern.
Example:
vmm listaliases example.com vmm listaliases %master@%
vmm listrelocated [pattern]
This command lists all defined relocated addresses. Relocated entries belonging to alias-domains are prefixed with a '-', addresses of regular domains with a '+'. The output can be limited with an optional pattern.
To perform a wild card search, the % character can be used at the start and/or the end of the pattern.
Example:
vmm listrelocated example.com vmm listrelocated %master@%
vmm listusers [pattern]
This command lists all user accounts. User accounts belonging to alias-domains are prefixed with a '-', addresses of regular domains with a '+'. The output can be limited with an optional pattern.
To perform a wild card search, the % character can be used at the start and/or the end of the pattern.
Example:
vmm listusers example.com vmm listusers %master@%
vmm listpwschemes
This subcommand lists all password schemes which could be used in the vmm.cfg as value of the misc.password_scheme option. The output varies, depending on the used Dovecot version and the system's libc.
When your Dovecot installation isn't too old, you will see additionally a few usable encoding suffixes. One of them can be appended to the password scheme.
Example:
vmm listpwschemes
Usable password schemes
-----------------------
CRYPT SHA512-CRYPT LDAP-MD5 DIGEST-MD5 SHA256 SHA512 SSHA512
SKEY SSHA NTLM RPA MD5-CRYPT HMAC-MD5 SHA1 PLAIN SHA CRAM-MD5
SSHA256 MD5 LANMAN CLEARTEXT PLAIN-MD5 PLAIN-MD4 OTP SMD5
SHA256-CRYPT
Usable encoding suffixes
------------------------
.B64 .BASE64 .HEX
vmm version
Prints vmm's version and copyright information to stdout. After this vmm exits.
vmm domainadd fqdn [transport]
Adds the new domain into the database and creates the domain directory.
If the optional argument transport is given, it will override the default transport (domain.transport) from vmm.cfg. The specified transport will be the default transport for all new accounts in this domain.
Configuration-related behavior:
domain.auto_postmaster
When that option is set to true (default) vmm will automatically create the postmaster account for the new domain and prompt for postmaster@fqdn'spassword.
account.random_password
When the value of that option is also set to true, vmm will automatically create the postmaster account for the new domain and print the generated postmaster password to stdout.
Examples:
vmm domainadd support.example.com smtp:[mx1.example.com]:2025 Creating account for [email protected] Enter new password: Retype new password: vmm cs account.random_password true vmm domainadd sales.example.com Creating account for [email protected] Generated password: pLJUQ6Xg_z
vmm domaindelete fqdn [force]
This subcommand deletes the domain specified by fqdn.
If there are accounts, aliases and/or relocated users assigned to the given domain, vmm will abort the requested operation and show an error message. If you know, what you are doing, you can specify the optional keyword force.
If you really always know what you are doing, edit your vmm.cfg and set the option domain.force_deletion to true.
vmm domaininfo fqdn[details]
This subcommand shows some information about the given domain.
For a more detailed information about the domain the optional argument details can be specified. A possible details value can be one of the following six keywords:
accounts
to list the e-mail addresses of all existing user accounts
aliasdomains
to list all assigned alias domain names
aliases
to list all available alias e-mail addresses
catchall
to list all catch-all destinations
relocated
to list the e-mail addresses of all relocated users
full
to list all information mentioned above
Example:
vmm domaininfo sales.example.com
Domain information
------------------
Domain Name......: sales.example.com
GID..............: 70708
Domain Directory.: /srv/mail/c/70708
Quota Limit/User.: Storage: 500.00 MiB; Messages: 10,000
Active Services..: IMAP SIEVE
Transport........: lmtp:unix:private/dovecot-lmtp
Alias Domains....: 0
Accounts.........: 1
Aliases..........: 0
Relocated........: 0
Catch-All Dests..: 1
vmm domainquota fqdn storage [messages] [force]
This subcommand is used to configure a new quota limit for the accounts of the domain - not for the domain itself.
The default quota limit for accounts is defined in the vmm.cfg (domain.quota_bytes and domain.quota_messages).
The new quota limit will affect only those accounts for which the limit has not been overridden. If you want to restore the default to all accounts, you may pass the keyword force.
When the argument messages was omitted the default number of messages 0 (zero) will be applied.
Example:
vmm domainquota example.com 1g force
vmm domainservices fqdn [service ...] [force]
To define which services could be used by the users of the domain – with the given fqdn – use this subcommand.
Each specified service will be enabled/usable. All other services will be deactivated/unusable. Possible service names are: imap, pop3, sieve and smtp.
The new service set will affect only those accounts for which the set has not been overridden. If you want to restore the default to all accounts, you may pass the keyword force.
vmm domaintransport fqdn transport [force]
A new transport for the indicated domain can be set with this subcommand.
The new transport will affect only those accounts for which the transport has not been overridden. If you want to restore the default to all accounts, you may pass the keyword force.
Example:
vmm domaintransport support.example.com dovecot:
vmm domainnote fqdn [note]
With this subcommand, it is possible to attach a note to the specified domain. Without an argument, an existing note is removed.
Example:
vmm do example.com Belongs to Robert
An alias domain is an alias for a domain that was previously added with the subcommand domainadd. All accounts, aliases and relocated users from the domain will be also available in the alias domain.
In the following is to be assumed that example.net is an alias for example.com.
Postfix will not accept erroneously e-mails for [email protected] and bounce them back later to the mostly faked sender. Postfix will immediately reject all e-mails addressed to nonexistent users.
This behavior is ensured as long as you use the recommended database queries in your $config_directory/pgsql-*.cf configuration files.
vmm aliasdomainadd fqdn destination
This subcommand adds the new alias domain (fqdn) to the destination domain that should be aliased.
Example:
vmm aliasdomainadd example.net example.com
vmm aliasdomaindelete fqdn
Use this subcommand if the alias domain fqdn should be removed.
Example:
vmm aliasdomaindelete e.g.example.com
vmm aliasdomaininfo fqdn
This subcommand shows to which domain the alias domain fqdn is assigned to.
Example:
vmm adi example.net
Alias domain information
------------------------
The alias domain example.net belongs to:
* example.com
vmm aliasdomainswitch fqdn destination
If the destination of the existing alias domain fqdn should be switched to another destination use this subcommand.
Example: vmm aliasdomainswitch example.name example.org
vmm useradd address [password]
Use this subcommand to create a new e-mail account for the given address.
If the password is not provided, vmm will prompt for it interactively. When no password is provided and account.random_password is set to true, vmm will generate a random password and print it to stdout after the account has been created.
Examples:
vmm ua [email protected] "A 5ecR3t P4s5\(rs/\(rs/0rd" vmm useradd [email protected] Enter new password: Retype new password:
vmm userdelete address [force]
Use this subcommand to delete the account with the given address.
If there are one or more aliases with an identical destination address, vmm will abort the requested operation and show an error message. To prevent this, specify the optional keyword force.
vmm userinfo address [details]
This subcommand displays some information about the account specified by address.
If the optional argument details is given some more information will be displayed. Possible values for details are:
aliases
to list all alias addresses with the destination address
du
to display the disk usage of the user's mail directory. In order to summarize the disk usage each time this subcommand is executed automatically, set account.disk_usage in your vmm.cfg to true.
full
to list all information mentioned above
Example:
vmm ui [email protected] Account information ------------------- Address..........: [email protected] Name.............: None UID..............: 79881 GID..............: 70704 Home.............: /srv/mail/2/70704/79881 Mail_Location....: mdbox:~/mdbox Quota Storage....: [ 0.00%] 0/500.00 MiB Quota Messages...: [ 0.00%] 0/10,000 Transport........: lmtp:unix:private/dovecot-lmtp SMTP.............: disabled POP3.............: disabled IMAP.............: enabled SIEVE............: enabled
vmm username address [name]
The user's real name can be set/updated with this subcommand.
If no name is given, the value stored for the account is erased.
Example:
vmm un [email protected] "John Doe"
vmm userpassword address [password]
The password of an account can be updated with this subcommand.
If no password was provided, vmm will prompt for it interactively.
Example:
vmm up [email protected] "A |\(rs/|0r3 5ecur3 P4s5\(rs/\(rs/0rd?"
vmm usernote address [note]
With this subcommand, it is possible to attach a note to the specified account. Without an argument, an existing note is removed.
Example:
vmm uo [email protected] Only needed until end of May 2012
vmm userquota address storage [messages]
This subcommand is used to set a new quota limit for the given account.
When the argument messages was omitted the default number of messages 0 (zero) will be applied.
Instead of storage pass the keyword domain to remove the account-specific override, causing the domain's value to be in effect.
Example:
vmm userquota [email protected] 750m
vmm userservices address [service ...]
To grant a user access to the specified services, use this command.
All omitted services will be deactivated/unusable for the user with the given address.
Instead of service pass 'domain' to remove the account-specific override, causing the domain's value to be in effect.
Example:
vmm userservices [email protected] SMTP IMAP
vmm usertransport address transport
A different transport for an account can be specified with this subcommand.
Instead of transport pass 'domain' to remove the account-specific override, causing the domain's value to be in effect.
Example:
Assumed you want to use Dovecot's dsync(1) to convert a user's mailbox from Maildir format to mdbox format, you can tell Postfix to retry later.
vmm ut [email protected] "retry:4.0.0 Mailbox being migrated" # convert the mailbox ... then set the transport to Dovecot's lmtp vmm ut [email protected] lmtp:unix:private/dovecot-lmtp
vmm aliasadd address destination ...
This subcommand is used to create a new alias address with one or more destination addresses.
Within the destination address, the placeholders %n, %d, and %= will be replaced by the local part, the domain, or the email address with '@' replaced by '=' respectively. In combination with alias domains, this enables domain-specific destinations.
Examples:
vmm aliasadd [email protected] [email protected] vmm aa [email protected] [email protected] [email protected] vmm aa [email protected] postmaster+%[email protected]
vmm aliasdelete address [destination ...]
This subcommand is used to delete one or multiple destinations from the alias with the given address.
When no destination address was specified the alias with all its destinations will be deleted.
Example:
vmm ad [email protected] [email protected]
vmm aliasinfo address
Information about the alias with the given address can be displayed with this subcommand.
Example:
vmm aliasinfo [email protected] Alias information ----------------- Mail for [email protected] will be redirected to: * [email protected]
vmm relocatedadd address newaddress
A new relocated user can be created with this subcommand.
address is the user's ex-email address, for example [email protected], and newaddress points to the new email address where the user can be reached.
Example:
vmm relocatedadd [email protected] [email protected]
vmm relocatedinfo address
This subcommand shows the new address of the relocated user with the given address.
Example:
vmm relocatedinfo [email protected] Relocated information --------------------- User `[email protected]' has moved to `[email protected]'
vmm relocateddelete address
Use this subcommand in order to delete the relocated user with the given address.
Example:
vmm relocateddelete [email protected]
vmm catchalladd fqdn destination ...
This subcommand allows to specify destination addresses for a domain, which shall receive mail addressed to unknown local parts within that domain. Those catch-all aliases hence "catch all" mail to any address in the domain (unless a more specific alias, mailbox or relocated entry exists).
WARNING: Catch-all addresses can cause mail server flooding because spammers like to deliver mail to all possible combinations of names, e.g. to all addresses between [email protected] and [email protected].
Example:
vmm catchalladd example.com [email protected]
vmm catchallinfo fqdn
This subcommand displays information about catch-all aliases defined for a domain.
Example:
vmm catchallinfo example.com
Catch-all information
---------------------
Mail to unknown localparts in domain example.com will be sent to:
* [email protected]
vmm catchalldelete fqdn [destination ...]
With this subcommand, catch-all aliases defined for a domain can be removed, either all of them, or those destinations which were specified explicitly.
Example:
vmm catchalldelete example.com [email protected]
/root/vmm.cfg
will be used when found.
/usr/local/etc/vmm.cfg
will be used when the above file doesn't exist.
/etc/vmm.cfg
will be used when none of the both above mentioned files exists.
dsync(1), transport(5), vmm.cfg(5)
