Somehow it ran okay when I copied and modified the example
conf file with the same changes.  I guess you have to
explicitly turn on pop3 now.  Here is the log output:

It isn't setting egid to 12(mail) like it should.

Thanks for your help.

What about IMAP and dotlock files?  I need dotlock files for
inbox and all the folders to keep openwebmail from trying to
change the folders while an IMAP connection is open.  It's
probably not too likely in our scenario anyway so it won't
be a showstopper, but is that possible?
