In my case, I see a few different kinds of messages. I posted a sequence earlier. Here it is again. At least one of each unusual message I see is included in this two minute period, and these are all the dovecot messages in that period and the initial message is the first unusual one that occurred.

The scenario here is a remote machine connects every five minutes via an SSH tunnel and retrieves and deletes (with fetchmail pop3) all the mail for 4 users.
