Sandy,

Well, I haven't yet given up.  For one, I could ask that VAMSoft if they could allow for header tagging of this type.  There is another kludge though that I am thinking might be of use here...

With a recent IMail release, you can now set up peering to use RCPT TO to test incoming messages for valid senders.  You could set up each gateway domain to peer off of the ORF enabled instance of MS SMTP for validation with RCPT TO, and then it would handle delivery according to your host file settings (MS SMTP has better queue settings anyway).  As long as IMail does envelope rejection for peered domains that fail validation, this setup should work.  I do understand of course that this would be somewhat limiting in terms of capacity due to the delay while checking the RCPT TO, however if installed on the same box or network, this should be very quick.

I'm hoping that down the line IMail will have the ability to do envelope rejection for gatewayed domains, and if that comes, you could just strip out the MS SMTP/ORF part without needing to totally retool your environment.

What do you think?

Matt

In  the  same  vein, yes (though actually part of an existing compiled
sink that we wrote).

  
This  is  how  they  add headers to the messages containing the MAIL
FROM  and RCPT To data. I get the feeling from reading the code that
they  are  using some sort of pre-normalized data that MS SMTP spits
out,  though  I'm  not  at  all  sure about that.
    

Yes, MS SMTP's envelopefields collection is all normalized, and that's
all   that's   available   after   submission.   That's   what  I  was
double-checking,
