Like I said I use Opera Mail…
Following instructions from the help file i did this on my avast4.ini
[MailScanner]
DefaultPopServer=mail.myserver.com
DefaultSmtpServer=mail.myserver.com
ShowTrayIcon=1
UseDefaultSmtp=1
AutoSetProtection=0
And on Opera I change the pop and smtp servers to 127.0.0.1… its working fine… but just for me… for the others users isn’t working…
