mail() php sendmail sending to gmail not working-CodePudding

Ubuntu 20.04 sendmail PHP 7.4 SPF DKIM1 DMARC1 all set correctly

trying this:

<?php
$to      = '[email protected]';
$subject = 'some subject testing object';
$message = 'hello, this is un message';
$headers = 'From: "Something here" <[email protected]>' . "\r\n" .
    'Reply-To: "Reply to" <[email protected]>' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

var_dump(
mail($to, $subject, $message, $headers)
);
?>

the output of this is true, obviously and try to see in the logs what happened. This worked before in ubuntu 16.04. After upgrade I have to setup mail server again in the VPS.

in the logs we've seen this. I have checked in google and the trouble seems to be in SPF1 but i've allowed the VPS domain also and doesn't work.

CodePudding user response：

after seeing some options in mail() php manual, i've seen there is a way to set manually the domain sender. Is not the best way but is a patch is working now for gmail:

mail($to, $subject, $message, $headers, " [email protected]")

the unspace between the mail and "-f" it's intended. AFter this, GMail is not returnend my mails. The mails get into spam, that's another fight to make, but now they're turned into.
