PHP mail function does not send email to a valid account in the same domain

Question

I use the mail function as follows:

mail($emailto, $subject, $body, $headers);
mail('[e-mail]', $subject.' / '.$emailto, $body, $headers);

The first is intended for the end user. The second instance is for me to keep records.

Sometimes the end user provides his email address, and sometimes his space.

• When an email address is provided, the end user actually receives the email without any problems.
• However, no emails are sent to [e-mail] in the case of EITHER - I also checked the spam folders.

In my / mail / new folder, I see many FILES created similarly to the ones below. The error is incorrect because [e-mail] is the VALID email address (setting up with Google for domains).

  This message was created automatically by mail delivery software.

  A message that you sent could not be delivered to one or more of its
  recipients. This is a permanent error. The following address(es) failed:

    [e-mail]
      No Such User Here

  ------ This is a copy of the message, including all the headers. ------

Answer 1

Two things:

• You should check to see if there is any remaining $emailtobefore the actual function call mail. You do not want PHP trying to send mail to an empty address.

• [e-mail] , , - (mysite.com), , "" , - , Google Apps. (, sendmail) , "".

Answer 2

(, , hotmail/gmail Outlook/Thunderbird)?

- .

- , - (, , ?).

Answer 3

If you use sendmail , go to the configuration file and using MX records to point to Google Apps like me do the following

sudo vim /etc/mail/sendmail.mc

add this:

FEATURE(`relay_based_on_MX')dnl

restart sending mail

sudo /etc/init.d/sendmail restart
