sending a virus from mailscanner's domain is undetectedbutincoming mail from either our domain or others is detected

[Matt Doherty]

Our emails are being scanned for outgoing mail now.
I got it working..
And It had nothing to do with our ISP or our DNS

 Thanks

    Hello,
    No not on the machine running mailscanner, but outlook 2000 on a
workstation sent an email to an outside domain with a virus to test and the
outside domain received it with the virus in tact.. Its the test virus you
referred me earlier to use.. when I reply (from the outside domain) and its
incoming to mailscanner, it will pick it up then. only incoming scanning is
taken place not outgoing.
    Thanks!

  Did it get any X-MailScanner: header at all?
  If not, then it probably didn't go via the MailScanner server.
  If it did, then what did the header say? What is in your mailscanner.conf
file?

  Unless it is told to, MailScanner doesn't care what addresses are in the
email message.

      Did you run the email client program on the machine that is running
      MailScanner, by any chance? If so, did you make the email program talk
SMTP
      to localhost:25 or did it invoke sendmail directly?


      MailScanner (when running with sendmail) can only scan mail coming in
the
      SMTP port. There is no way (with sendmail) of scanning mail poked
directly
      at the sendmail binary.
