It appears you have SMTP setup to use TLS/SSL with "Verify SMTP peer name" enabled in the phpBB SMTP settings, but the host mail.mblforum.com resolves to is setup with a certificate issued to mboxhosting.com and not mail.mblforum.com.phpBB Debug] PHP Warning: in file [ROOT]/includes/functions_messenger.php on line 1617: stream_socket_enable_crypto(): Peer certificate CN=`mboxhosting.com' did not match expected CN=`mail.mblforum.com'
The quick workaround would be to simply turn off "Verify SMTP peer name", and live with the slightly weakened security posture of not being able to verify the host is whom you expected. And maybe that's the long term solution too, if you find you don't have control over how that certificate is provisioned.
If your host provides PHP "mail()" function support, another workaround or long term solution could be to just turn off SMTP use by phpBB, and instead rely on using the PHP mail() function support provided by your host.
Only your hosting provider could tell you for sure whether you (or they) are able to change the certificate to match the DNS name of the server. Or whether there is a different DNS name provided by your host you could use for SMTP, which would match the configured certificate.
If you installed a different phpBB instance on this same server and it doesn't demonstrate the same behavior, then I would have to guess this second instance is not configured to use SMTP, or is using a different SMTP server, or isn't configured to use SSL/TLS for SMTP, or doesn't have "Verify SMTP peer name" enabled.
