Hi, this is my first post to the list after years of passive following
every now and then.
Dovecot: 2.0.13 (3d07ab746a67) prebuilt binaries from xi.rename-it.nl
OS: i686 Debian 6.0 squeeze/sid
I am about to run a setup where users are virtual and their mail is owned by
vmail user. I bumped into minor client issue and needed to enable rawlogging
according to http://wiki2.dovecot.org/Debugging/Rawlog
This is what was printed to log at first try:
Jun 29 21:46:25 (null)Fatal: This process must not be run as root
I changed service postlogin to contain "user = vmail" and above
error disapperead. I also tried "user = dovecot" which seem to work
as well.
Is vmail or dovecot user more appropriate for raw logging?
>From wiki I got the impression that user must be same as the effective UID
of logged in user, which in my setup is vmail(121).
Also, maybe the (null)Fatal -message could be improved(?).
