XF 2.2 Server error log: ErrorException: Email to / from failed: [E_WARNING]

[_Al]

Hi all,

I'm hoping someone can assist me here. I have set up AWS SES to handle emails from my board. I get this error:

    ErrorException: Email to CUSTOMER EMAIL from ADMIN EMAIL failed: [E_WARNING] stream_socket_enable_crypto(): Peer certificate CN=`SERVER-IP-ADDRESS.cprapid.com' did not match expected CN=`email-smtp.eu-north-1.amazonaws.com' src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:94

I have confirmed that emails are working from my server and AWS SES shows both the domain and email address are verified, so I think the issue lies somewhere within xenForo. Has anyone had a similar issue? How did you fix it? Thanks.

This is due to cPanel SMTP restrictions being enabled.

Aye. Thanks @Jeremy P - they have removed the restrictions (on the second time of asking, initially they said the issue was with xenForo!).

I'm now just waiting for AWS SES to move me to production mode and I'm keeping my fingers and toes crossed that it sorts it.
