qmail and multilog

[magnetik]

Hello,

just wondering, is there any reason why Plesk 7.5 does not setup qmail to use multilog from the daemontools package by default?

As suggested by qmail author D. J. Bernstein here:

http://cr.yp.to/qmail/faq/admin.html#multilog

All my reading has told me that splogger is slower and chews CPU - which I wanted to avoid with the amount of email qmail is sending out (I have a few newsletter clients doing 5000+ emails a day successfully). Also multilog handles log rotation automagically.

I have successfully installed daemontools from an RPM (and disabled svscan) and tweaked my qmail install to use it - works fine. I have also done some other qmail tweaks to improve the queue - like dropping the queuelifetime of a message to 1 day (instead of 7) and turned off all bouncebacks of unknown mail - to avoid "double bounces".

Keen to discuss this topic with others and the reasons why Plesk does not use multilog out of the box.

Yes let's open this discussion because it looks like one of the best utilities for analyzing qmail needs to use multilog:

How do you turn off bouncebacks of unknown mail?

How do you turn off bouncebacks of unknown mail?

Here are some tips for fine tuning this and other parameters:

Run Brent Meshier's Greylisting Qmail Plesk patched with maxrcpt patch, then you can:

Add maxrcpt in control folder to limit number of recipients

More fine tuning:

Add queuelifetime as 259200 (3 days, the default is 7)
Add bouncefrom username, e.g. postmaster
Add doublebounceto to user, e.g. joebloggs
Add doublebouncehost, e.g. domain.com

Double bounces will now go to that address. It's probably a good idea to see why you have double bounces, especially if you have a lot.

I've also seen people use a '#' as the doublebounceto in order to avoid double bounces taking up queue space.

Your original question about Qmail and Multilog and Plesk remains, and I see multiple people are asking the same question with no answer.

maxrcpt is built into Plesk Linux from version 8.4 see here http://kb.odin.com/en/1411
