My PHP mail() function is now working! System Info: Running PHP on webserver running Apache, Postfix(for SMTP) and running on CentOS linux. SMTP is working because I can do telnet localhost 25. My phpinfo() webpage gives the following information: ----------------- . sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i SMTP localhost localhost smtp_port 25 25 . ---------------Additional Information---------------------- I did a tail of the /var/log/maillog. Here are the lines that were generated after I tried to execute the mail script: (I replaced my real domain name with mydomain.com here) -------------------------------------- Apr 4 07:04:08 75-126-255-51 postfix/pickup[9377]: CC931CF006B: uid=48 from=<apache> Apr 4 07:04:08 75-126-255-51 postfix/cleanup[19815]: CC931CF006B: message-id=<[email protected]> Apr 4 07:04:08 75-126-255-51 postfix/qmgr[13998]: CC931CF006B: from=<[email protected]>, size=641, nrcpt=1 (queue active) Apr 4 07:04:08 75-126-255-51 postfix/local[19817]: CC931CF006B: to=<[email protected]>, relay=local, delay=0.04, delays=0.03/0/0/0.01, dsn=5.1.1, status=bounced (unknown user: "services") Apr 4 07:04:08 75-126-255-51 postfix/cleanup[19815]: D2BC9CF006C: message-id=<[email protected]> Apr 4 07:04:08 75-126-255-51 postfix/qmgr[13998]: D2BC9CF006C: from=<>, size=2306, nrcpt=1 (queue active) Apr 4 07:04:08 75-126-255-51 postfix/bounce[19818]: CC931CF006B: sender non-delivery notification: D2BC9CF006C Apr 4 07:04:08 75-126-255-51 postfix/qmgr[13998]: CC931CF006B: removed Apr 4 07:04:08 75-126-255-51 postfix/local[19817]: D2BC9CF006C: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=0.01, delays=0/0/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) Apr 4 07:04:08 75-126-255-51 postfix/qmgr[13998]: D2BC9CF006C: removed ---------------------------------------- What can we infer from this log file? One more thing, the mail() script is trying to send an email to [email protected] address. It seems to me from this log that the email id [email protected] doesn't exist, however it is not true. I can send email to this address from any normal mail service.
it seems from the logs that you have made the domain local and yet this domain is on another server that is why postfix trys to deliver locally but the user does not exist.
