sgiorgetti, do I understand it correctly that your mail server resides on the same machine? (I.e. you’re sending emails just to this local mail server, not outside)?

Then it would behave as expected, because by default, local-only connections are not scanned.

But connections outside (i.e. probably from Wingate to a remote server) should be scanned OK. Can you confirm this?

BTW You can change the described behavior by adding the following line to the [MailScanner] section of the file \data\avast4.ini:

IgnoreLocalhost=0

Thanks
