XF 2.3 SMTP wrong version number (Postmark)

[Salamanca]

Hi,

I'm getting this error when trying to use Postmark:

Symfony\Component\Mailer\Exception\TransportException: Email to ********@gmail.com from forum@******.com failed: Connection could not be established with host "ssl://smtp.postmarkapp.com:25": stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:0A00010B:SSL routines::wrong version number
src/vendor/symfony/mailer/Transport/Smtp/Stream/SocketStream.php:154
Generated by: Unknown account

This error happens with Xenforo 2.3
With Xenforo 2.2 (on the same server) it works.

Thanks

I can't be the only one with this issue?

Try using port 587 with the Use SSL/TLS box checked ? You've got it set to port 25.

Yes, I already tried that:

• Connection could not be established with host "ssl://smtp.postmarkapp.com:587": stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:0A00010B:SSL routines::wrong version number

For this particular error it seems you are as there have been no other reports of it.

It looks like the issue is SSL related.

Contacting Postmark may help, as with this other issue: https://xenforo.com/community/threads/smtp-tls-version-sending-through-postmark-errors.222883/

Try unchecking the Use SSL/TLS option with the port set to 587
