If you have a good deal on a powerful VPS you wish to run
as a relay, suggest you rent a second dirt-cheap low resource
VPS for email.  MTA softwares tolerate flaky connectivity
and system performance well.

RBLs are a fact of life.  I use them to great benefit on
my MTAs.  Reason no-port-25 exits are blacklisted is that
web-form spammers use them.

Here are two excellent resources for viewing the blacklist status
of IP addresses (helpful to check IPs, when known, before

http://multirbl.valli.org/lookup/x.x.x.x.html  # single IP
https://www.senderbase.org/lookup/?search_string=x.x.x.x/24  # block, directs to Talos

The lists which matter most are Spamhaus, CBL and Barracuda.

Good luck with it!
