Hi i have tried the http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu9.04 and it is working great. The only problem that i have is that when i send a email that contains a .exe file then i will not get a email that says the email was rejected due to virus ot the email will not be cleaned. The email will just disapear, the send will ot recieve it an it will not be send back. When i send email to non existing user then i also dont get a reply that the users could not be reached. i get no email Can someone maybe help me and tell me how to configure clamav and spamasasin to send the sender a notify email when email was rejected, cleaned or when address is not reachable or incorrect. Thank you
