Hi,
Several of my clients (and I) have the same issue: Avast 6 Pro blocks outgoing e-mails without any warning. The e-mails will just reside in the outbox until you disable Avast.
We’re all running Win7 64-bit and use Outlook 2007 or Outlook 2010.
One solution I found online was to disable SSL, but that didn’t help. There’s no warning message from Avast at all.
The outgoing email server use port 587.
I hope this can be resolved ASAP.
Thanks.
Cato
