I started dealing with this several years ago using Perl. The closest I got with sendmail was to check that the call worked, and if it didn't try again up to 5 times.
For me, bottom line, if you want to do what you are trying to do, use something besides sendmail. I switched to Qmail, and have successfully sent 15,000+ personalized messages, one at a time, with both Perl and PHP. (It takes a couple hours, but it does work.) Of course I only send opt in email, and I hope you are doing the same, as spam is always evil. :) HTH, Peter Janett New Media One Web Services ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New Upgrades Are Now Live!!!
