Thanks to everyone for their suggestions. Here's what I've figured out and where I'm stuck: I had my email domain listed in the "mydomains" line of main.cf. That's why the mails were only being handled on my local machine and not going out to the proper SMTP server. I took it out and was able to send a test message by telneting into localhost. However, when I try to send a mail through PHP, it gets rejected on the grounds of "unknown user account" on the server. Further investigation reveals PHP is using www-data as it's user and, for whatever reason, it's not using the name I specify in the $headers variable of my PHP script... Here's the script I'm using:
$to="[email protected]"; $subject="Test"; $body="Testing"; $headers="From: [email protected]\r\nReply-to: [email protected]"; $mail_sent=@mail($to,$subject,$body,$headers); echo $mail_sent ? "Message sent." : "Message failed."; And here's the tail of mail.log: Sep 26 18:10:26 pspicer-ubuntu postfix/pickup[26062]: 4039E849A7: uid=33 from=<www-data> Sep 26 18:10:26 pspicer-ubuntu postfix/cleanup[27047]: 4039E849A7: message-id=<20110926221026.4039E849A7@pspicer-ubuntu> Sep 26 18:10:26 pspicer-ubuntu postfix/qmgr[26063]: 4039E849A7: from=< [email protected]>, size=372, nrcpt=1 (queue active) Sep 26 18:10:26 pspicer-ubuntu postfix/smtp[27049]: 4039E849A7: to=< [email protected]>, relay=192.168.1.6[192.168.1.6]:25, delay=0.14, delays=0.14/0.01/0/0, dsn=5.0.0, status=bounced (host 192.168.1.6[192.168.1.6] said: 573 [email protected] unknown user account (in reply to MAIL FROM command)) Sep 26 18:10:26 pspicer-ubuntu postfix/cleanup[27047]: 622DC849A8: message-id=<20110926221026.622DC849A8@pspicer-ubuntu> Sep 26 18:10:26 pspicer-ubuntu postfix/qmgr[26063]: 622DC849A8: from=<>, size=2236, nrcpt=1 (queue active) Sep 26 18:10:26 pspicer-ubuntu postfix/bounce[27050]: 4039E849A7: sender non-delivery notification: 622DC849A8 Sep 26 18:10:26 pspicer-ubuntu postfix/qmgr[26063]: 4039E849A7: removed Sep 26 18:10:26 pspicer-ubuntu postfix/smtp[27049]: 622DC849A8: to=< [email protected]>, relay=192.168.1.6[192.168.1.6]:25, delay=0.13, delays=0.05/0/0/0.08, dsn=5.0.0, status=bounced (host 192.168.1.6[192.168.1.6] said: 550 [email protected] unknown user account (in reply to RCPT TO command)) Sep 26 18:10:26 pspicer-ubuntu postfix/qmgr[26063]: 622DC849A8: removed See where it says "from=<[email protected]> and not [email protected] I specify in the script? Anyone have an idea why? I'm still trying to turn something up in Google...
