<p>I thought I had, and I do. OVH is allocating my PTR in a group of
8 addresses (<b>ip-54-39-185.eu.</b>). May be that's where the
problem lies? I sent a ticket to OVH.<br>

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.

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.
<br>
<br>
Is it possible to run one's own mail server this days?
