Trouble sending an email with the PHP mail function. Full trace provided

I have a simple script setup:

<?php
mail('corgan1003@aol.com', 'Hello World', 'Testing a message');
?>

I cannot send email from my server to AOL accounts. The error details are below. GMail lets me send the message...so I guess AOL is just a bit stricter.

Do you know how I can make the FROM parameter come out correctly? Setting the FROM header in the PHP mail function does not work.

UPDATE

This little hack is working but I would prefer to fix this issue outside of PHP.

mail('corgan1003@aol.com', 'Hello World', 'Testing a message', null,'-faddress@domain.com');

I am super noob with mail servers

From serverfault Tony

• With AOL they often won't go through unless you fill out the form to get white listed. To change where the mail is coming from, edit the sendmail_path parameter in the php.ini file. This is mentioned in the php mail() doc under additional_parameters.

  For Example:

  sendmail_path = "/usr/sbin/sendmail -t -f me@kyle.com"
  

  You can also pass instead a parameter to the mail() function:

  <?php
  mail('nobody@example.com', 'the subject', 'the message', null,
     '-fwebmaster@example.com');
  ?>
  

  Lastly, you might find alternative mail package more flexible, such as PEAR MAIL package or msmtp, you can specify other smtp servers.

  Tony : right now i am using phpmailer because the site is wordpress based and it comes stock. only issue is i have to change a wordpress file to create this setting which is bad practice. i would like to know how to fix this in postfix settings. it would be great to have postfix use the virtual host name as a host as well.

• Try escaping the at sign.

  mail('corgan1003\@aol.com', 'Hello World', 'Testing a message');
  

  From John Gardeniers

• You want to change the envelope From: address, which is different from the From: header. See this comment in the mail() function's doc.

  The envelope address depends on your MTAs configuration - in your case, 'www-data' is the user your script runs as, and 'com' is (part?) of your machine's hostname. Assuming you are on *nix, you can try to override the envelope address like this:

  mail('corgan1003@aol.com', 'Hello World', 'Testing a message', null,'-faddress@domain.com');
  

  where address@domain.com is the envelope sender address you want to show.

  If that works, and you have access to your php.ini file, you can set the envelope sender address there - see Kyle's post.

  You might also want to have a look at your MTAs (sendmail, postfix) configuration - looks like it has a problem with your hostname setting. Changing php-s settings will fix it for php, but if something else (cron, logwatch) on your system wants to sent mail, it would be helpful to have a working MTA.

  Edit after your comment: It's hard to suggest anything without knowing your mail server's config, but for a start, try the following:

  myhostname = mail.virtualhostname.com
  mydomain = virtualhostname.com
  myorigin = $mydomain
  masquerade_domains = virtualhostname.com
  

  Tony : yes, i would rather fix this for postfix and not just PHP. the postfix configuration file is huge though. all i really want is the FROM field to be "noreply@virtualhostname.com". I set myorigin = $mydomain but that did nothing. Maybe you could provide some direction?

  Tony : my mail server's config is the default postfix installation. i haven't done anything fancy. adding these attributes to the config does not seem to change the envelope's FROM address
