Do you have reverse DNS records set up -- this is pretty much a
requirement for running any mail server these days.
This mailing list kept getting blocked by Spamhaus when we used IPv6
address to send out mail. I have no idea what was wrong with that, but
the minute I turned off IPv6 everything went back to normal.
I remember there's an open-source mail config/blacklist checking website
tool, but I don't remember its name.

Does anyone has insights about dealing with Spamhaus?
I'm getting increasingly frustrated by being listed without
explanation. I run a very low bandwidth mail server and a website for
my business. I am running postfix with SPF, DKIM, and DMARC. I'd like
to know what I am missing.
Spamhaus is very popular which in turn affects Twitter, LInkedIn,
beyond just the mail.
Is it possible to run one's own mail server this days?
