A less than elegant solution as an alternative to deleting the message, is to hold the data phase pending the scan.
Contrary to your vision of this option, it is not only elegant; it happens to be the *correct* thing to do. Dropping the message on the floor is arguably stretching the bounds of RFC2821. If a message is going to be dropped because of a policy (such as a worm/virus flag), you really should be rejecting after DATA with a RFC1893 5.7.x extended result code.
Another solution would be not returning message content within a DSN.
If you're still sending to a forged address, how is this not still UBE...? -- -- Todd Vierling <tv () duh org> <tv () pobox com> <todd () vierling name>
