Bug #4363: mail() Subject header not functioning correctly

From: sgibson@digitalimpact.com Operating system: Linux (RedHat 6.2) PHP version: 3.0.14 PHP Bug Type: Misbehaving function Bug description: mail() Subject header not functioning correctly I was using the mail() function to send mail. It seems to be misbehaving on my system. System information: Apache 1.3.12 PHP 3.0.14 RedHat Linux 6.2 Sendmail 8.10.0 php3.ini: sendmail_path = /usr/sbin/sendmail -t When I call the mail() function, like this: mail( $to, $subject, $message); The subject is not correctly set. Instead, the contents of $message is used for the subject. It seems to be about 64 to 68 (or so) bytes of $message are used in the subject, then the remainder of $message is in the body. Looking at the message in the mailbox, it appears that the "Subject:" is set to null, then a second "Subject:" line is created, with the above mentioned actions. When I test this on: UnixWare 7.0.1 Apache 1.3.6 PHP 3.0.6 Sendmail 8.9.1 it seems to function correctly. When using additional headers (after the message), they get appended to the body of the email, and not set in the message header. Very very odd behavior. I didn't see any other bug reports regarding this, or any feature fixes within 3.0.15 or 3.0.16. It may be an environment thing. I.E. Sendmail 8.10.0 and PHP 3.0.14?? v/r Shane
