Enough mail servers require a reverse DNS  to accept incoming messages 
that running a mail server without a reverse DNS setup correctly will 
block you from lots of mail destinations.
Years ago I learned this lesson the hard way.

If all you care about is this mail list and a hand full of other 
locations then run your mail server from home with no reverse.

If you can find a properly setup forwarder then you may be able to have 
that site resend your messages.

Also lots of ISP's filter outbound smtp connections.

I have hated Spamassassin for years but I still use it.
I will have to take a look at rspamd.
