Hi 200011,
it would realy help if You provide us with more detials of Your setup

  • Which OS are You using
  • Mail Client
  • Avast Version
  • any othe Application for Spam filtering

In general Avast does not support SSL connections, except You use as e-mail client Outlook (not Outlook Express) or The Bat - for these clients special Plugin’s are used.

How Avast can be used with other mail clients and SSL can be found in this thread:

Peter
