MTA/TLS

Hello.

My scheme: Internet -> MTA -> Exchange.
Letters that come to the MTA from outside must be TLS-encrypted.
I added a certificate to the MTA, but I can not check whether the checkmark is checked-use TLS (the interface has moved down).
In this case, smtp test via mxtoolbox shows that the command 250 STARTTLS is not sent from the MTA server.
Is it possible to check whether the starttls is enabled via clash?

Re: MTA/TLS

I do not think the question really belongs in this section but ok.

To make sure your TLS cert is correctly setup and all other settings are ok and TLS is working, use this site to check.

It will give you a list of all steps it takes and will compare the hostname, the MX record, the reverse DNS and the SMTP response all to the TLS supplied name.

Re: MTA/TLS

I agree, this this probably better in Threat Prevention‌ as that's what makes most use of the MTA.
