Hi,

We have been running the free version for quite some time and are about to buy the network professional edition, but I need someone from Zimbra to verify if this is a bug or not prior.

Small company ~25 employees, Secure IMAP and SMTP setup. Not many webmail users, mostly outlook/entourage few thunderbird and evolution. About every 2-3000 email sent, smtp auth quits working - SASL gives the same old PLAIN LOGIN failed messages and I have to restart zimbra and it goes right away.

I could not find a post here on the subject, so thought I would ask.

If it is not a known bug, I will be more than happy to provide logs.

-Greg
