Hi:
I have been using Dovecot for well over a year now and it has always worked with
few
problems. The mail setup is not simple...
Postfix+MailScanner+ClamAV+Docvecot+MySql+postfix.admin... just to mention the
major
things. The system is CentOS 5.3 on VMware. The maildir is on an NFS share,
index and
control is local.
About a month ago I thought I upgraded from 1.1.x to 1.2.x. by doing an rpmbuild
and
deploying. I say thought because today I determined the binaries were still
1.1x. Today
a reboot was done after a kernel upgrade (2.6.18-128.x -> 2.6.18-164). The
mail system
never came back up. My assumption is that the working binaries were in memory
but the
images on disk were changed.
Anyway, the problem is with deliver writing to the mail dir. The error is:

If you delete the directory it does get recreated. I upgraded to 1.2.5 but it
did not
help. There were a lot of errors in the audit.log, however SELinux was already
in
permissive mode and switching it to disabled did no good. I created the
following policy
to get rid of all of the errors in the audit log:

Note to all: If you are running Dovecot on a system where any of the mailboxes are nfs v4 mounted from a RHEL (or derivative) server DO NOT upgrade that server to an unpatched 2.6.18-164 kernel, it is very broken at this time. Not only will Dovecot fail but you're likely to have a myriad of other problems. https://bugzilla.redhat.com/show_bug.cgi?id=523797 https://bugzilla.redhat.com/show_bug.cgi?id=524520> On Mon, 2009-10-05 at 10:30 -0400, vwc72283 at voicenet.com wrote: >> So, it is reproducible.
