I have zimbra running for a while with domain jimmy.com (for sake of simplicity). jimmy handles mail for jimmy and all the MTA and advertised names are jimmy.com or mail.jimmy.com .
I recently added a few domains and seeing SASL authentication failing once I try to set them up from outlook. Once I check SMTP authentication required, I get the infinite dialog box asking username/pass and behind the scene trying to authorize and if I do not check the SMTP authentication on outlook, I get 'relay access denied'.
Any easy way to solve this ? I have exhausted the faqs.
