I have a problem getting mail from my university's IMAP server. I have found that if you try to use STARTTLS in your client, connection hangs forever. I reported the problem, but they didn't solve it.

Now, my real problem is that even if I disable Outlook 2010's security, Avast antivirus, acting as a man-in-the-middle with Outlook, activates the STARTTLS option, causing Outlook to hang.

If I temproarily disable Avast, I can download the email without using the secure protocols, but I don't like turning my antivirus on and off every time.

My question is

How to prevent Avast from using the STARTTLS protocol with IMAP? Please notice that I can't use POP3 as I share mail across computers.

Thank you


I believe this should work if you uncheck SSL for inbound and outbound mail.

Tools -> Accounts -> Mail -> Properties -> Advanced -> uncheck SSL

Also, this article might help you find other places SSL/TLS gets enabled in Avast.

    Some systems won't work with SSL unchecked. – AndrejaKo Jan 23 '11 at 16:44
  • Thanks for that AndrejaKo. I've added an article from Avast Support Center that shows where else you can enable or disable SSL/TLS. Hopefully, djechelon can play around with those settings if my intial solution does not work correctly. – Paul Jan 23 '11 at 16:50
