Configuration causes phpmailer to throw a deprecation warning in php 8.1

I can't seem to replicate the problem with 10.1.7 and the default contact form. I've cleared the timeout field and don't see any errors with PHP 8.1.16. I've tried logged in and logged out with the contact form and also the test submission on the settings page.

Is there anything else which can trigger an error?

Thanks for the report. Does this fix it for you?
