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.
