Troubleshooting PHP Mail
That is quite a long story. A few bullet points (Assuming that mail() returns true and there are no errors in the error log) :
- Does the sender address ("From") belong to a domain on your server? If not, make it so.
- Is your server on a blacklist (e.g. check IP on spamhaus.org)? This is a remote possibility with shared hosting.
- Are mails filtered by a spam filter? Open an account with a freemailer that has a spam folder and find out. Also, try sending mail to an address without a spam filter.
- Do you possibly need the fifth parameter "-f" of mail() to add a sender address? (See mail() command in the PHP manual)
- If you have access to log files, check those, of course, as suggested above.
- Do you check the "from:" address for possible bounce mails ("Returned to sender")? You can also set up a separate "errors-to" address.
For german speakers, I have written a quite exhaustive "what to do" on this issue some time ago. See here.
PHP mail not working for some reason
This is probably a configuration error. If you insist on using PHP mail
function, you will have to edit php.ini
.
If you are looking for an easier and more versatile option (in my opinion), you should use PHPMailer.
PHP Mail Not Sending But No Errors
Try this to find out where is the problem
$success = mail('example@example.com','New Enquiry',$msg);
if (!$success) {
print_r(error_get_last()['message']);
}
with a glance at Php Mail Documentation
Note:
When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini.
Failing to do this will result in an error message similar to Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing. The From header sets also Return-Path under Windows.Return Values
Returns TRUE if the mail was successfully accepted for delivery, FALSE
otherwise.It is important to note that just because the mail was accepted for
delivery, it does NOT mean the mail will actually reach the intended
destination.
update
After comments just for test, remove every code in your php file an just try the simplest way to debug
<?php
// the message
$msg = "First line of text\nSecond line of text";
// use wordwrap() if lines are longer than 70 characters
$msg = wordwrap($msg,70);
// send email
if(!mail("someone@example.com","My subject",$msg)){
var_dump(error_get_last()['message']);
}
?>
PHP mail stopped working
Could it be that E-Mails are being sent fine, but are caught by a spam filter?
If this could be, allow me to cross-post myself:
