PHP uses either the system's sendmail wrapper or SMTP depending on
your php environment, server OS, and php.ini settings. The SMTP
version of mail() is only available on Windows systems. In your case,
using mail() is the same as sending the mail message via sendmail from
a shell. This means that the mail is injected into the postfix queue
after the after-queue content filter. Your best bet for a workaround
is to use the PHPMailer or PEAR Mail packages to send your messages
via SMTP to localhost.
Good luck!
