Marc, I actually had thought of this. The probably lies in the server who
originates the first callout. If you use a MAIL
FROM:<calloutcheck@mydomain>, you beter besure that absolutely no blocks are
placed on that address when the server you do that callout to calls back to
you. There will be 2 callouts in this case. If you instead do checks on
that address, then you will inturn do another callout. You'll runinto a
loop. It would be your responcibility to prevent this from happening. When
a check is to your callout@mydomain address, you could set a flag to deny
the email after data because afterall, this address never sends mail.
