Thanks for debugging it, Farfouille.
What is set for your [/i]default[/i] smtp server into avast4.ini file?
Technical, it is very cute to thank me but I have to confess that I'm a software developper and that kind of problem always ring my professional bell...
Well the laptop I used to make the test is now far away from home (it is not mine, i had it to ... install avast). So I can't look into the avast4.ini but I remember well that when I configured the smtp alert avast asked me for the smtp server and the originator mail. I entered the same smtp server as the ISP which is 'free' (smtp.free.fr).
If you guess that it can be a configuration problem with the smtp server or mail adresses set up for the alert, let me tell you that you are right to think of such a problem but I've double checked that and it was ok. Btw when an infected mail was detected (and take a long time to be processed), I received the alert (I am the receiver). If I can find some time I will make some further test with my adsl connection using the smtp alert.
Eric do you use the smtp alert feature of avast when an infected mail is received ?
