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

Question

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.

Edit:

mail.log

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

Edit2: PHP - Just grabbed from documentation. FYI, I removed my e-mail.

<?php
// 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);

?>

Edit3: 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 0.0.0.0 port 25: Address already in use

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

root@server:/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
root@server:/etc/postfix# kill 23554

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

Answer 1

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
