That's just the problem---according to the IMAP spec (or IMAPS), there's a 30 minute time-out between when you authenticate and when non-traffic will force you to re-authenticate. What that means is that if you authenticate, according to the IMAP spec you don't have to re-authenticate for a very long time.
Thanks for all, guys,
just a question: as you say, Kyle, the possible workaround maybe is set $RELAYCLEAR=30 minutes?
thank you very much Regards Andrea
