Usage

Overview

mailsync is a command line tool to keep collections of mailboxes synchronized. Mailboxes can reside on the local filesystem or on an IMAP server.

mailsync can be invoked in three ways:

mailsync channel

Synchronizes two sets of mailboxes. In c-client taxonomy, a library on which mailsync relies to implement mailbox access, mailboxes are referred to as "stores".

mailsync store

Lists the contents of a store. It's recommended to execture this command before synchronizing two stores to check whether mailsync is seeing what you are expecting it to see.

mailsync channel store

Lists what has changed in a store since the last sync.

Options

-f file

Use alternative config file.

-n

Don't delete messages when synchronizing.

-D

Delete any empty mailboxes after synchronizing..

-m

Show from, subject, etc. of messages that are killed or moved when synchronzing.

-M

Also show message-ids (turns on -m).

-s

Says what would be done without doing it (turns on -n). Attention: this will change the "Seen" flag of emails and will create new, empty mailboxes in order to be able to compare them.

-v

Show IMAP chatter.

-vb

Show warning about braindammaged message ids

-vw

Show warnings

-vp

Show RFC 822 mail parsing errors

-h

Show help.

-d

Show debug info. -di Debug/log IMAP protocol telemetry. -dc Debug config.

-t mid_type

Use mailsync with specified message-id algorithm. Currently you have the choice between md5 and msgid (default). msgid uses the Message-ID in the mail header to identify a message. md5 calculates a MD5 hash from the "From", "To", "Subject", "Date" and "Message-ID" headers and uses that as message identifier.

If you use mailclients and servers that allow empty Message-IDs (f.ex. in mail drafts) then you should use the md5 algorithm.
