email – How can I get PHP mail() to work? Need help configuring a MTA

Posted by: admin July 12, 2020 Leave a comment


Update: I solved it. Documented everything below.

I tried so many things, but it just would not work.

I wouldn’t mind using, postfix, exim4, or sendmail. I just need a step by step guide and explanation of what am I doing. I am also using Google Apps for e-mail.



Nov  3 01:14:02 mugbear postfix[16615]: error: to submit mail, use the Postfix sendmail command
Nov  3 01:14:02 mugbear postfix[16615]: fatal: the postfix command is reserved for the superuser

What does this mean?

Update to edit: Fixed by correcting sendmail_path in php.ini with sendmail_path = /usr/sbin/sendmail -t -i

PHP – Just grabbed from documentation. FYI, I removed my e-mail.

// The message
$message = "Line 1\nLine 2\nLine 3";

// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70);

// Send
mail('[email protected]', 'My Subject', $message);


Another error:

Nov  3 07:22:29 mugbear postfix/postdrop[17131]: warning: unable to look up public/pickup: No such file or directory
Nov  3 07:22:29 mugbear postfix/postdrop[17133]: warning: unable to look up public/pickup: No such file or directory

Update to edit3: Fixed this with the following link: http://ubuntuforums.org/showthread.php?t=666018
Run this:

sudo mkfifo /var/spool/postfix/public/pickup
sudo /etc/init.d/postfix restart

After that, you’ll get this error:

 postfix/master[13902]: fatal: bind port 25: Address already in use

Then you will have to check your processes and kill sendmail processes, for example:

[email protected]:/etc/postfix# ps aux | grep mail
root     23554  0.0  0.0   8232  1900 ?        Ss   10:17   0:00 sendmail: MTA: accepting connections          
root     27308  0.0  0.0   3004   764 pts/0    S+   10:30   0:00 grep mail
[email protected]:/etc/postfix# kill 23554

What does this mean?

Nov  3 07:34:51 mugbear postfix/pickup[17309]: 6602F1C151: uid=33 from=<www-data>
Nov  3 07:34:51 mugbear postfix/cleanup[17311]: 6602F1C151: message-id=<[email protected]>

Name service error for name=xen.prgmr.com type=A: Host found but no data record of requested type)

Update to edit4: I ran, dpkg-reconfigure postfix and selected Internet Site.

How to&Answers:

did you properly installed postfix ? If yes :
service postfix restart

nano /etc/php.ini

Find sendmail_path , change the line to sendmail_path = /usr/sbin/sendmail.postfix -t -i

Here is the complete server / client installation instructions for php client also http://setahost.com/installing-postfix-as-a-default-mail-sending-program-with-php/

follow client installation instructions …


What isn’t working? What do server logs show (both for PHP and mail)? You need to figure out if the problem is with PHP or your MTA.

IMHO, setting up send-only postfix and then using the PEAR Mail library is probably the best bet.
