Greetings folks. I seem to be having a problem with PHP's mail()
function and sending 'From' headers properly. Here's my setup:
I have a site I set up for a client that has a form their clients
can fill out to submit some data. When the form is submitted, I have
PHP gather the data and create the body of an email which is then
sent to both the owners of the site and back to the person who
submitted the data. Because the server hosts multiple sites, I am
sending an additional 'From' header so the email doesn't appear to
come from the hostname of the server itself (nobody@xxxxxxxxxxxxxx).
Because I did not have a DNS entry for my hostname, the 'domain does
not exist' error I'm seeing in the bounce emails is correct. I do
not wish to keep a DNS entry for it (I have added one as a temporary
fix), as that doesn't fix the 'From' header issue to begin with, so
I would appreciate it if you did not make that suggestion.
As per PHP's documentation of the mail() function, I am sending the
header like so:
"From: sender@xxxxxxxxxxxxx\r\n"
I am getting bounce emails from certain ISPs (AOL, Roadrunner, some
local ISPs) saying the sender's domain does not exist. It seems that
either mails are coming from my hostname (nobody@xxxxxxxxxxxxxx), or
those ISPs are reading the additional headers incorrectly.
Unfortunately, this is not acceptable. People aren't getting their
emails, and the hammer is coming down on me.
As far as I know (based on the lack of bounce emails), this worked
fine on PHP4, but with our new webserver (running PHP5), I'm
experiencing problems. Far as I can tell, the mail() function has
not changed between versions.
I'm stumped here and need to get this fixed asap. I've tried 'From'
and 'FROM', tried a 'Name Here <name@xxxxxxx>' format, and tried
terminating with double newlines with and without the carriage
return. Nothing seems to work. I've even gone so far as to edit
php.ini with a default from address, but that doesn't appear to have
fixed anything either.
The ISPs are likely looking at the envelope sender rather than the
sender specified in the headers.
If you're on a box using sendmail (which I think you are based on what
you've said) you can set this using the 5th parameter to mail set to -
f followed by the email address you want to use.
i.e. '-fsender@xxxxxxxxxxxxx'
I believe this is covered on the manual page for the mail function.
