Other Information

I’m using Mybb and I get this error when I try to send an email via SMTP. Is there a problem with fsockopen() on the hosting side?

Hi STasaR,

@STasaR

Uncaught Error: Call to undefined function fsockopen()

Socket-related functions are disabled here afaik. Use API-based methods for email instead.

Cheers!

As part of the PHP 8.2 upgrade, the fsockopen function is disabled. This doesn’t prevent you from using SMTP though, PHPMailer and Symfony Mailer both use stream_socket_client for SMTP, which is very similar and does just work.

I don’t fully understand why fsockopen is blocked but stream_socket_client isn’t, so I’ll check with iFastNet what can be done about it.
