Description

I'm using a shared hosting on OVH : https://www.ovhcloud.com/en/web-hosting/shared-hosting/

When sending a message with dns set to sendmail://default or native:default,I get the errors but the mail is sent !

Error message with dns set to sendmail://default :

Fatal error: Uncaught Symfony\Component\Mailer\Exception\TransportException: Process failed with exit code -1: in /home/mvggxek/www/v27/lib/comp-vendor/symfony/mailer/Transport/Smtp/Stream/ProcessStream.php:60 Stack trace: #0 /home/mvggxek/www/v27/lib/comp-vendor/symfony/mailer/Transport/Smtp/SmtpTransport.php(272): Symfony\Component\Mailer\Transport\Smtp\Stream\ProcessStream->terminate() #1 /home/mvggxek/www/v27/lib/comp-vendor/symfony/mailer/Transport/Smtp/SmtpTransport.php(359): Symfony\Component\Mailer\Transport\Smtp\SmtpTransport->stop() #2 /home/mvggxek/www/v27/plugins/l21_emailSuite/index.php(46): Symfony\Component\Mailer\Transport\Smtp\SmtpTransport->__destruct() #3 /home/mvggxek/www/v27/plugins/index.php(56): include_once('/home/mvggxek/w...') #4 /home/mvggxek/www/v27/templates/admin/2021/index.php(72): include_once('/home/mvggxek/w...') #5 /home/mvggxek/www/v27/admin/index.php(74): include_once('/home/mvggxek/w...') #6 {main} thrown in /home/mvggxek/www/v27/lib/comp-vendor/symfony/mailer/Transport/Smtp/Stream/ProcessStream.php on line 60

Error message with native:default :

Is that a bug ? It seems to be. Please tell me how could I handle that ?

I can't update to latest version (7.x) for compatibility reason with PHP 7.4+.

Thanks

5.4.21 is quite old. Do you observe the same behaviour with 5.4.40?

Thanks for the quick reply. I'll try that and let you know

After update to v5.4.40, I get the following error when sending email, with DNS set to 'sendmail://default' AND email is not sent :

After update to v5.4.40, I get the following error when sending email, with DNS set to 'native://default' BUT email is sent :

For your information sendmail_path is set to '/usr/sbin/sendmail -t -i' on global PHP config.

I'm using 7.4.33, but I experienced the same issue with v8.x. When I fall back to swiftMailer, everything works well on the same web hosting.
