I am running 4.10.24 with mysql replication on four production
machines. The only problem we are seeing is about once every
5 days one of the machines locks up. We have not found out why
yet. It might be hardware failure. The symptoms are we see
a large (600+) number of qmail-local, vchkpw and vdelivermail
programs. None of which can be killed. The machine can not
be rebooted since they can not be killed. This might be an
NFS problem or a kernel problem (linux 2.4.5, nfs v3). I don't
think it is a mysql problem since mysql is still happily
replicating. I am going to upgrade to the latest devel version
sometime tomorrow.

I applications waiting on an NFS service can hang. However
the NFS volume is mounted:
rsize=8192,wsize=8192,timeo=14,intr
I think the intr value says the application can be interrupted.

Today I switched one of the machines to mount with:
rsize=8192,wsize=8192,timeo=14,intr,soft,nolock
Perhaps the soft mount will allow the apps to be killed.
I also turned off locking since it is not needed.

Besides this vpopmail appears to be stable. If you do use it
in production, monitor the mailing list and new releases and
the ChangeLog.

I had to put up those disclaimers up on the web site since
someone called up inter7.com and was really pissed cause they
used a devel release with the cdb module and it had a newline
bug in it, and it *fucked* up thier system.
