I'm thinking about running a small web & email

fixed IP address (only IPv4, we don't have an IPv6 address).
I'm wondering if anyone knows of any issues we might come across. For
instance, will people like spamhaus recognise it as a residential IP and
blacklist it because of that?
Andy has written how you can check this yourself. You can also use
https://www.dnsbl.info
and enter your static IP address at the top of the page. It will check
multiple RBLs, including the Spamhaus ones.
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 :)
Cheers,
Mike
