and enter your static IP address at the top of the page. It will check
multiple RBLs, including the Spamhaus ones.
That's a good page, it also checks all.s5h.net, which is hosted partly
in BitFolk, and free to query.
It depends on the ISP, too. I'm with Andrews &
Arnold and they don't
block any incoming or outgoing ports and my static IPs (both v4 and
v6) have never been blacklisted. Many ISPs block incoming and outgoing
port 25 (SMTP).
I have a mail server at home which I've been running for over 20 years with
a domain that now attracts tons of spam. However, with blocklists and Exim's
pre-delivery checks it's very rare that any spam actually gets through
(maybe one every two or three months).
SPF/DKIM/DMARC are necessary nowadays and I've never had issues delivering
to Gmail and Hotmail/Outlook.com addresses.
Having said all that, my main email address(es) are hosted with Fastmail and
ProtonMail. I find as I get older that I don't have the energy to do
absolutely everything myself :)
Part of the problem with outbound mail on residential networks is that
the BLs and receiving servers will spam-score or just block based on the
fact that it came from residential IP blocks.
Consider the wit of the average internet user, their ISPs have a lot of
work to do keeping the netblocks free of abuse, that's just too much
from a tenner a month subscription, they just don't have the man power,
and probably don't get good results from trying to educate people that
don't want to learn.
For that reason, I sort of sympathise with the likes of online web mail
providers to downgrade residential mail, but at the same time, it
penalises those who are capable of running mail from home.
