I have been trying off and on for the better part of a year to get a dovecot server migrated from one machine to another. It is currently working on CENTOS and we are trying to get it on Redhat. Currently I have everything migrated and working in IMAP, but we have one client device that requires POP3 (doesn't support IMAP). To this end, we have set up everything to work in POP3 as far as I can tell.

In the dovecot.conf file, we show:

protocols = imap imaps pop3 pop3s protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

The services running include:

dovecot-auth imap-login imap-login imap-login pop3-login pop3-login pop3-login

Everything else looks good including the logs which seem to show proper connectivity - messages are being received, accounts are connecting and disconnecting, etc. but the pop connections are not (apparently) passing messages found in that box. They are still just sitting there, not being read, picked up, or otherwise delivered by dovecot. Any ideas on what else I can check or change to get this to pick up?

Thanks, Tom Higgins
