On my DirectAdmin (1.37) VPS, I'm having a problem with the mailserver.
As response to the EHLO command, the server shows amongst others 250-STARTTLS
When the mailserver connecting to it, does a STARTTLS as response to this I get a
454 TLS currently unavailable.
For most mailserver, this means that they will fall back to a none-TLS connection and send mail via that. However some mailservers are not that clever and will simply stop the mailsending. This means that some mailserver are not able to send mail to my mailboxes (hosted on the DirectAdmin system).
Is it possible to disable this STARTTLS part, so that within the EHLO response the DirectAdmin system no longer via that 250-STARTTLS?
