Php mail function not working after plesk update

[Niels van de rWal]

Hi,

After updating Plesk from 11.x to 12.5, the mail() function doesn't work anymore.
I can sent mail with Outlook (imap) and webmail, but on a website I can't.
I tried it with the mail() function, but also the phpmailer class don't work.
The mail() function always returns false. (no errors)

After searching hours for a solution, I hope you can help me?

Greetings

The following ways to e-mail are also working:
- Sending from SMTP with phpmailer class
- Sending from SSH after logging in as root

Yes I did, no mail received and the function returns false.

Make sure that you have enabled option "Allow users and scripts to use Sendmail" in Tools&Settings -> Mail Settings

I did that.

Check that you haven't this function in php disabled_functions option for this subscription.

Check that you haven't this function in php disabled_functions option for this subscription.

This is in my php.ini:

; This directive allows you to disable certain functions for security reasons.
; It receives a comma-delimited list of function names.
; http://php.net/disable-functions
disable_functions =

Hi Niels van de rWal,

if you would like help with your investigations, consider to add depending entries from your mail - log ( /var/log/ ) . It helps as well to include depending entries from your apache and/or nginx - logs, located at "/var/www/vhosts/system/(SUB)DOMAIN.COM/logs/", if you use scripts.

Same problem here after upgrading from 11.5 to 12.5.
The strange thing is that trying to send with
<?php
// Send email
mail("test@test.tld","hello","test mail function");
?>
as suggested by Igor, the e-mail arrives.

But all wordpress forms and Others script sending mail for all domains on the server don't work.

Someone can help us?

I'm trying using the CHECK MAIL plugin for wordpress and i got important info looking to log files:

[Mon Nov 07 16:15:46 2016] [warn] [client xxx.xxx.xxx.xxx] mod_fcgid: stderr: PHP Warning: stream_socket_enable_crypto(): SSL operation faile, referer: http://www.MYDOMAIN.com/wp-admin/tools.php?page=checkemail

So it seems that new php 5.6 verifies SSL certificates by default. Look here: https://github.com/PHPMailer/PHPMailer/issues/368
In this thread there is explanation to avoid this test but is also explained that is better to fix SSL verification... but how to do that?

So... no answers... so i change the question. New servers with a native Plesk 12.5 panel have already a SSL certificate installed? Or they have a different php.ini configuration in order to avoid PHP 5.6 checkings on ssl?
I'm going crazy with this problem...
