Yes, you're right. It's not my mta. I do some testing and found out
that the milter-ahead terminated the connection right after the rcpt to
negotiation if the mail account doesn't exist; no data is received by my
I was also testing MailScanner in debug mode and feeding the virus email
manually (via telnet). MailScanner let the virus mail through and the
console return MailScanner error:
----- begin MailScanner output -----
mxgw# /usr/local/etc/rc.d/mailscanner.sh start
In Debugging mode, not forking...
SA bayes lock is /root/.spamassassin/bayes.lock
Bayes lock is at /root/.spamassassin/bayes.lock
format error: can't find EOCD signature

Stopping now as you are debugging me.
----- end MailScanner output -----
I tried to send the virus mail as attachment of eml file out to my
hotmail account, but my mail server virusscan quarantined it. I also
tried to send it directly to the mail gateway and my hotmail did receive
it without problem. That is MailScanner didn't intercept it as virus
mail. The error message is the same as above.
At least I've narrowed down the problem now. Do you still want me to
send it to you (as attachment eml)? Or Julian wants it too?
btw, I've switched my gateway with a new box running latest FreeBSD 5.4
and MailScanner 4.43.8. I'm using the old box as testing now.
