I used to disable my firewall & antivirus to get email out. Then I narrowed it down to Avast.
With Avast disabled Outgoing email worked w/ firewall enabled.
Then I narrowed it down to Avast WebShiled…
I did the whole thing w/ ports in MailShield, but w/ MailShiled enabled w/ whatever port setting that I have, email only goes out w/ Outlook.exe excluded in Web Shield (or disabled).
Is this the correct solution in my case? (My outgoing port IS port 80)
