Thanks for the link. All my settings seem to be ok.]
Incoming mail works OK.
Outgoings mail is the problem.
If I go to mail shield settings and uncheck “Scan outgoing Mail (SMTP)” Everything works, but that is not the best solution.
In you’re Thunderbird settings make sure you have ‘Connection Security’ set to NONE for both server setting and outgoing server in you’re thunderbird, and in you’re Avast SSL accounts make sure you have choose SSL for POP / SMTP / IMAP and let me know.
Can you confirm how to get to Avasti SSL accounts to choose SSL POP / SMTP / IMAP ?
I ask because in the link you provided there dos not appear to be a “Expert Settings” or SSL accounts in Avasti 8
Okay goto Avast and click onto the tab called ‘Security’ on the left side look for ‘Antivirus’, than click onto ‘Mail Shield’ and click onto setting tab on the right top side of the ‘Mail Shield’ and look for ‘SSL Scanning’.
