BS with the DNS configuration ..
The send alert when recipient has opend the mail is an M$ idea put into
Exchange
Sendmail at the time i did this anti-virus solution did not support this M$
idea..
the exchange server was sending mail without the correct to: blah blah
header
so it was looping back to root and postmaster forever in a day because
amavis was fireing round the loop on the 1st sendmail.cf file ....
post fix and qmail under amavis i believe run 2 instancies of the mta that
work togetther to recieve the mail then check it for viruses.
the sendmail solution is simply 2 sendmail cf's one that recieves checks it
gives it back to sendmail runs the normal second cf to send the mail on its
way.

well we or you do not set the rules Exchange is used out there with open

really thats a little irrelevent

well since my advice is based on a real life scenario i guess u dont have
any grounds to judge,
since this mail was not to you personally, I dont see why u posted any how
if you had a problem with it you could simply delete it ...
