mailping-cron - run periodic processing to test email service availability and functioning




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.

Setting up a circuit
1. Give a name to the circuit, hereafter referred to as circuit.

2. Arrange for a local email address to be delivered to maildir
/var/lib/mailping/state/circuit/incoming/. See mailping-store.

3. 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.

4. You're done! Munin should now see the data.

Testing multiple servers
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 <mailping+that@this.example.com> is delivered with mailping-store to

Remote address <echo@that.example.com> is an alias that redirects all email to

/etc/mailping/that/to is set to <echo@that.example.com>.
