I’ll try to state the whole case simply:

MDaemon E-Mail Server sits on ports 25/110

Avast.ini is set to:

PopListen=127.0.0.1:111
SmtpListen=127.0.0.1:26
ImapListen=127.0.0.1:144
DefaultPopServer=127.0.0.1:110
DefaultSmtpServer=127.0.0.1:25

OE sends on port 26 and receives on port 111

Everything was fine until today’s update.

Now,

outgoing e-mail is scanned twice (and two clean messages inserted)
incoming e-mail is scanned once (and “sporadically” clean messages are inserted but not always)

If I put everything back to normal, outgoing e-mail gets scanned only one time, but incoming does not get scanned at all.

That’s it in a nutshell…
