Guys,
How to configure my qmailtoaster to use port 587 SMTPS Submission for my
clients and port 25 for other servers from internet ? Some like this....
--CLIENTS----- port smtp/587---------------------> **************
* SERVER *
--OTHER INTERNET MAIL SERVERS --- port 25---> * QMAILTOASTER *
* *
--CLIENTS ----- port 25 ----***BLOCKED*** ***************
Thanks for help

The stock QMT supports TLS on port 587 for submission, although there is
no way to enforce TLS. Authentication is required though.
SMTPS (port 465) is deprecated, and not implemented in the stock QMT. If
you really need it, there are instructions for implementing it on the wiki.
I don't know of a way to block clients from using port 25. Never heard
of such a thing, and honestly can't think of a reason why you might want
to do this. If a client uses port 25 and authenticates, I think the
processing is the same as if they used port 587. Someone please correct
me if I'm wrong about this.
