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.

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? ;)
