Hi,
I'm trying to find out how to do traffic accounting with Dovecot 2.x, preferrably v2.0.9, preferrably on CentOS 6.
I've previously asked on IRC, but there was little feedback, and my understanding is now this list is the preferred media for such inquiries. If I recall correctly, some weeks ago I was told that traffic accounting is not officially supported on Dovecot 2, but that there could still be ways to get it to work, but no details were provided.
I can think of the following approaches:
rawlog, preferrably piped (if that's possible?) into something like wc to prevent privacy issues and to reduce the I/O overhead
maildrop filtering in front of dovecot LDA (for mail inbound to mail storage)
sieve filtering
Unfortunately I have little experience with either so far, so it's hard to make a good choice. I would appreciate hints on these approaches, and on any other approaches you can think of, as well as any related documentation / how-to you could point me to.
While I'm subscribed to the list (for mail authentication purposes), I've disabled receiving any e-mail form the list, so please CC me on any replies.
Thanks in advance,
Moritz
