PHP Deprecated Errors in WP Error Log

I was doing some debugging unrelated to SolidMail, when I discovered that SolidMail is throwing a lot of warnings about deprecated functions when PHP version is 8.4 or later. I suspect you are aware of this, but figured I should report it, just in case.

Hello,
Thanks for flagging this!
We’re aware that PHP 8.4 introduces new deprecations and we’re working on compatibility. To help us address this properly, it would be really helpful if you could share the specific warnings you’re seeing.
If possible, please provide:
the exact deprecation messages
where they appear
your PHP and plugin versions
Looking forward to your response.
