The client is thunderbird. Correct me if I am wrong, it appears it 40 seconds for the client to hand over the email to the server? If so, where should I troubleshoot? are there maintenance tasks/configuration changes to improve this situation.
BTW... from the inception there was no or negligible delay. Several months later, I am seeing this on regular basis even hourly volume is not large.
