We currently use SparkPost to send emails via SMTP on our vB4.2.5 board. SparkPost are about to depreciate TLS 1.0. I've just tested their new non-TLS 1.0 server and, using TLS legacy, I received the following error:
The email log reports the following: "FAILED: Unable to negotitate TLS handshake."
If I switch to the other TLS option (TLS Native) I get this:
In this case, the email log reports the following: "FAILED: Unable to connect to SMTP server."
Is vB compatible with TLS 1.1 or above or is the problem due to the server configuration?
Code:
The mailing function returned an error while trying to send the mail. The following errors were outputted by PHP when attempting to send mail: PHP Warning: stream_socket_enable_crypto(): SSL: Success in ..../includes/class_mail.php on line 776 PHP User Warning: Unable to negotitate TLS handshake. in ..../includes/class_mail.php on line 715
If I switch to the other TLS option (TLS Native) I get this:
Code:
The mailing function returned an error while trying to send the mail. The following errors were outputted by PHP when attempting to send mail: PHP Warning: fsockopen(): SSL operation failed with code 1.
