Setting up a freeBSD email server

Posted August 9, 2021 178 views

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 —–
(reason: 554 5.7.0 Blocked - see

—– Transcript of session follows —–
… while talking to
<<< 554 5.7.0 Blocked - see
… while talking to
<<< 554 5.7.0 Blocked - see
554 5.0.0 Service unavailable

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.

I believe that DigitalOcean does not offer an SMTP relay as a service, as per this article here:

What I personally do is to use an SMTP service like SendGrid, they also have a free plan, that way they take care of the mail IP reputation:

When setting up a web site or application under your own domain, it is likely that you will also want a mail server to handle the domain's incoming and outgoing email. While it is possible to run your own mail server, it is often not the best option for a variety of reasons. This guide will cover many of the reasons that you may not want to run your own mail server, and offer a few alternatives.
