Well, we’re giving you free help and support… will you receive this into BitDefender Free version? Maybe I’m bitter today, maybe this is not the most sympathic thing to read, I mean, I’m feeling a bit stupid 
About your settings, seems ok but you should try the combinations and test as you get the port conflict. I can’t see any suggestion that I’ve not posted yet, except:
- Disable and remove the HTML converter you use.
- Configure your email account to work without avast.
- Then, let avast port be different from your spam killer, set the pop3 and smtp servers to 127.0.0.1 and test how should you write the user name:
username#pop.server
username@pop.server#pop.server
for instance.
After you can receive emails, we’ll go to the outbound (smtp) ones…
