Thank you very much for your prompt help yesterday. It seems like my maildrop is working now and tagging spam and viruses correctly. My /etc/maildroprc has a section to pass the email through spamassassin and clamassassin.

Now I would like to automatically remove all viruses. So should I add a check for "X-Virus-Status: Yes" and write

to "/dev/null"

or something like that? How do I remove an email right in maildrop? I also think I don't need to send a bounce message for the sender at all, since it's a virus, and viruses usually automate emails from fake addresses.

The piece of /etc/maildroprc concerning antispam and antivirus is below.

Thanks. Timothy.
