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

[Ray Healy (Data Net Services)]

I am probably wrong in your situation but I thought I would mention this

I had a similar situation where emails were not being scanned by MailScanner when sent through my RAQ but incomming messages where scanned OK if sent to my RAQ by someone else.

This was due to the email message being hijacked by the ISP I was connecting to and putting the message through their own mail server and not mine even though in the properties I had stated the address of my mail server. 
I do not know whether this is of any help or am I toytally off track

    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.
