I have whitelisted my customer IPs so they can now send via port 25 if
they desire. My support staff were starting to get frazelled by all
the calls they were receiving. I do not assign rPTR records for most
of my customers and with the default settings of spamdyke those emails
are rejected.
The submission port though seems to be requiring TLS according to what
my support techs (I don't talk directly to any of my customers
anymore) are telling me, and you are correct that it does not go
through spamdyke when using port 587. I am going to test at home and
see if I can send unencrypted. I have some customers that still have
versions of Outlook that do not support TLS.
port 587 is the submission port, and it should for sure require
authentication (not TLS), and in such case spamdike is not necessary.
You may activate TLS optionally (in the client side setup should be 'use
TLS if present' or 'do not use TLS').

The issue I still have not solved is my server requiring TLS on port
587. My old server did not (It was optional before and I cannot find
the
setting to make it optional again). require TLS on 587. I am sure as I
look through Spamdyke files I will find that option.

Let me see if I can clarify a couple things.
Port 587 requires authentication, but TLS is not required for smtp
(although TLS is highly recommended).
Spamdyke operates on port 25, and is not connected to port 587 in any
way. Running spamdyke on port 587 would be pointless, as port 587
requires authentication, and spamdyke bypasses all filters on
authenticated connections (in case any client program were to submit
using port 25).
Whitelisting certain IPs for relaying operational emails is not
uncommon. It's better to configure the client software to send with
authentication (and TLS), although that's sometimes not practical.
With this in mind, would you like to try again? ;)
