I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5.
Since both are v2.0.x there aren't any big differences in how they work.
Tha mail server uses mysql for the users database, and a local ldap for authentication. .. ./imaptest user=XXXXXXX pass=XXXXXXX secs=120 seed=123 mbox=./dovecot-crlf
Test if the difference is in authentication or non-authentication:
auth: imaptest user=XX pass=XX secs=120 seed=123 - select=0
non-auth: imaptest user=XX pass=XX secs=120 seed=123 logout=0
My guess is that it's authentication related.
