I am currently using a FreeBSD12.2 VPS on your system and want to set up an email relay so that I can email out rather than using domestic public services. I have done a minor test sending email out via the generic FreeBSD email system and have received a reject message as follows.
----- The following addresses had permanent fatal errors ----- email@example.com (reason: 554 5.7.0 Blocked - see https://support.proofpoint.com/dnsbl-lookup.cgi?ip=188.8.131.52)

This is typical of most public VPS provider IP addresses but need to know how to get past this. Firstly do you have an email relay I can use via your VPS solution.
I have tried to contact proof point but this will most likely get no where.
I’d appreciate any help you could offer.
