Hello everyone,

since a lot of time I have to send notifications using mailservers via port 25, not all of them have TLS support, a lot of mailservers have SSL support.

You can see it in a USG60W:

You can see the same on a Flex200H:

Is there a plan to introduce SSL SMTP usage?

Thanks a lot

    Why not use StarTTLS

    I think when you enable just TLS and change the port 465 that should work?

    Unfortunately not all hostings let you have all the possible configs.

    As you can see with standard port:

    With specific port 587:

    Giving back errors also when using 465 port:
