Run periodic processing to test email service availability and functioning
mailping-cron
mailping-cron processes incoming emails, updates status and sends out probe messages.
The idea is to configure multiple email “circuits”, send probe messages regularly, and see whether they complete the circuit and how long it took.
\h'-04' 1.\h'+02'Give a name to the circuit, hereafter referred to as circuit.
\h'-04' 2.\h'+02'Arrange for a local email address to be delivered to maildir /var/lib/mailping/state/circuit/incoming/. See mailping-store.
\h'-04' 3.\h'+02'Create a configuration for the circuit, by creating directory /etc/mailping/circuit.
If you need non-default sender and/or recipient addresses, create files from and to there, containing the sender and recipient addresses suitable for the circuit.
\h'-04' 4.\h'+02'You\'re done! Munin should now see the data.
To test functioning of more than one email server, arrange an email alias at a remote site pointing to an address on your server, and set the address of that alias here.
Here\'s an example of testing a system consisting of two email servers and everything in that path (smarthosts, primary MXs, virus checkers, etc.):
Local address <[email protected]> is delivered with mailping-store to /var/lib/mailping/state/that/incoming/.
Remote address <[email protected]> is an alias that redirects all email to <[email protected]>.
/etc/mailping/that/to is set to <[email protected]>.
/etc/mailping/circuit/from
Sender address for the probe emails. Default: <currentuserid@fullyqualifiedhostname>.
/etc/mailping/circuit/to
Recipient address for the probe emails. You must arrange for the email to eventually get delivered to the maildir /var/lib/mailping/state/circuit/incoming/. mailping-store will probably be useful in that. Default: <currentuserid+circuit@fullyqualifiedhostname>
/etc/mailping/circuit/admin
Admistrative address, set as Reply-To in probe messages. Default: do not add Reply-To.
/etc/mailping/circuit/interval
How often a probe message is sent, in seconds. Default: 600 seconds.
/var/lib/mailping/state/circuit/
Stored state for the probing.
/var/lib/mailping/state/circuit/junk/
Maildir used to store all messages in incoming that do not look like probe messages. Read and delete them regularly.
/var/lib/mailping/state/circuit/broken/
Maildir used to store all messages in incoming that do look like probe messages, but a corresponding pending entry cannot be found. Duplicated probe messages cause these. Read and delete them regularly.
MAILPING_CONFIGDIR
Override the location of the configuration directory. Default: /etc/mailping
MAILPING_STATEDIR
Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories named after the circuit name. Default: /var/lib/mailping
