I've seen a hint in his logs that tlsmgr does not exist in his configuration.
That is probably the real cause of that message. OP should let Postfix check
his configuration:

Add missing lines in master.cf (TLSMGR!!):
        postfix upgrade-configuration

General permission check:
        postfix check

After a reload the problem with tlsmgr should be fixed.

Then use names that exist for exactly that purpose:
example.com
example.net
server.example
...

There are some requirements for "real" mailserver:
- fixed ip address
- matching hostname and reverse lookup for that hostname
- working dns resolution

I would like to add basic knowledge about smtp protocol and server security
and monitoring, but that is probably wishful thinking... sigh (^-^)

It is difficult to help the OP because I still don't know what exactly he
tries to do and what he has available to work with.
