This post for Vlk fixed the problem. Thanks. I’m curious if this will be a recurring problem each time there is a program update? I did not have this problem when running 4.1.

Quote from Vlk:

"1. interception of the traffic by avast
2. actual scanning of the traffic

Unchecking the SMTP box in Internet Mail provider’s settings disables 2 but not 1. This is what you’re experiencing.

To prevent avast from doing 1 (which makes sense in your case as you’re using SSL), please open the file \data\avast4.ini, and to the [MailScanner] section, add the following line:

StartSMTP=0

Then restart the Internet Mail provider and everything should be all right. Sorry for the confusion.

Cheers
