I'm not sure why it's changing to postmaster for you. Now, the from header in
an MS DSN says, "From: postmaster(_at_)helo".
The phrase "Microsoft SMTPSVC" appears several places in the headers.
Does that indicate IIS 6 SMTP?
It would not be wise to reject mail from postmaster addresses. This is the
address I would expect people to contact me with and also the address I would
reply from. This is also the address I would use when contacting other
postmasters.
That's what I wanted to know. I'll just live with it.

I notice they have a load balancer. Perhaps the load balancer is
screwing up the MAIL FROM. The incoming mail server at their MX
says it's sendmail-8.13.2.
