One gotcha: if the message doesn't have a To: header, sendmail will add an Apparently-To header for every address in the envelope. (Someday I'll fix bulk_mailer to add a dummy To: header if one is missing.) Keith Moore > what's the best format of a 'dummy' header to use when sending > bulk mail ? I like to add: To: undisclosed-recipients:; It fulfills the RFC 822 requirement, and fools sendmail into not generating the Apparently-To header. Some sendmail configs will (incorrectly) try to rewrite the address, but that doesn't usually cause problems. (And when it does, it only causes problems for sites downstream from the broken mailer). Keith Moore From: Keith Moore <moore@cs.utk.edu> Subject: Re: Bulk_mailer? Date: Fri, 14 Apr 1995 21:47:27 -0400 Okay, I hacked my bulk_mailer program to add a To: undisclosed-recipients:; header to any message which lacks a To, Cc, or Bcc header. More general header-munging would be nice, but probably goes in a separate program. ftp://cs.utk.edu/pub/moore/email/bulk_mailer.* -- Keith Moore http://www.cs.utk.edu/~moore/ Computer Science Dept. / Univ of Tenn / 107 Ayres Hall / Knoxville TN 37996 > how did you solve the problem of two copies of each messages > being sent to everyone? > Hmmm, it only did that the first time I ran it but afterwards, it went smoothly.
