Bogus emails sent out by Qmail

Could anybody comment on how Qmail could generate 400 or more identical emails from a single PHP mail() script line? The emails to 15 people were sent correctly from my web server as they each displayed once only on my screen. Everybody, me included, received 100's of copies in 3 or 4 batches of varying sizes over a 4 to 5 hour period. This not the first time I've used the mail() function and have never had serious problems in the past. Here are 2 sample email headers. All qmails are invoked by the same uid 2526 Thanks for any help, Chris Return-Path: anonymous@hedo5.netrover.com Received: from hedo5.netrover.com (hedo5.netrover.com [205.209.16.80]) by river.netrover.com (8.9.3+Sun/8.7.3) with SMTP id PAA01609 for <grayt@netrover.com>; Sun, 7 Jan 2001 15:02:56 -0500 (EST) X-Envelope-From: anonymous@hedo5.netrover.com X-Envelope-To: <grayt@netrover.com> Received: (qmail 5604 invoked by uid 2526); 7 Jan 2001 20:59:37 -0000 Date: 7 Jan 2001 20:59:37 -0000 Message-ID: <20010107205937.5603.qmail@hedo5.netrover.com> To: grayt@netrover.com Subject: GoldGame News From: grayt@netrover.com X-UIDL: pBi!![JS!!i&E"!)=V!!
