There were two places in the code that tried to connect the SSL filter, e.g. do the TLS handshake, but only one changed stmp state to EHLO afterwards. Depending on timing, the wrong path was taken and the connection was hanging, waiting for a server reply to a command not sent. Do the upgrade to tls in one place and update connection filter and smtps protocol handler at the same time. Always transition to EHLO on success. Fixes #16189 Reported-by: Christian Schmitz Closes #16206 |
