Hello,
We've been running Cyrus for well over a year now supporting over
30,000 email accounts. We use a Murder setup, with virtualdomain
support. We also use socketmap to insure the user exists during the
smtp session.
We were previously using 2.2.12 with very good luck. No real issues to
speak up. There were some things in the 2.3 releases that I wanted,
replication, the murder changes, and the socketmap changes (to check
quota's). So we upgraded, after I did all the testing I could think of.
Issues:
1) Sendmail goes completely out in the weeds. This seems to happen
multiple times per day per frontend. Sendmail will spew "Deferred:
Connection reset by localhost" messages in maillog (like has been
mentioned in another thread). Unfortunately, I can't seem to get any
useful debugging information as to what the cause is. I suspect it has
something to do with lmtp as the problem was non-existant with 2.2.12
(tho earlier versions did have the problem, and I was never able to
figure out the cause with them either).
2) We use Horde/Imp as webmail for our customers. This has also, in
the past, been rock solid. Now with the upgrades users with large
emails (a meg or larger) seem to not be able to receive their email at
all through webmail (timeout). I can't seem to find the core issue
here either, very frustrating. Both the server with webmail on it, and
the Cyrus servers are on the same subnet, only seperated by a Cisco
switch (which has been test, and is in perfect working order).
#1 is a major major issue. It causes mail to be queue'd, sometimes for
long periods of time, and I can't seem to find a specific cause other
than it started after the upgrade.
Any suggestion would be very welcome by my dwindling sanity.
Thanks!
Lenny
