Nothing to See

An afunctional landing page for a domain that sends and receives email. As far as I know, we are not required to run a public website, but you apparently expect one. It is a convenient place to describe our services and policies.

Services

We provide restricted DNS (port 53) and SMTP (port 25) services for this domain. Restrictions are applied at connection time. The service will:

drop all connections from hosts listed in Spamhaus' DROP list
respond to requests for DNS for this domain from all other hosts
drop or deny SMTP connections from scanners, Tor exit nodes, bogons, listwashers and other spam support services ( see scanners), or some SpamHaus listees
drop, deny, or redirect to a spamtrap, SMTP connections from hosts on our private shitlist (AS, domains and networks that send nothing but shit; listed AS include 211252, 399471, 213035, 49254, 62904, 49532, 40676, 208843, 9009, 51167, 141995)
accept all other SMTP connections

Email Policies

If we accept a SMTP connection, we accept responsibility for mail created by that connection. We will responsibly reject some mail and drop others into a blackhole. We do not relay mail.

Mail sent from this domain to remote domains (outbound mail) is always personal. DO NOT ACCEPT COMMERCIAL OR BULK MAIL FROM THIS DOMAIN

Mail sent to this domain from remote domains (incoming mail), is:

accepted if sent to postmaster. Postmaster is tetchy about abuse;
dropped or rejected if determined to be spam, abandoned cart messages, phish and other slimy creatures; or
accepted and delivered to human eyeballs

Listwashing services continue to abuse SMTP on behalf of their spamming clients. We don't allow that. Many B2B cold email support pages recommend list washing services (after all, cold email is spam).

DNS Policies

The Internet is dual-stack but SMTP is very nearly IPv4-only. All SMTP servers including ours must support IPv4. We will support IPv6 when it benefits us to do so, but there is no such benefit now, or for the forseeable future.

This DNS server supports SMTP services for a domain. It provides needed records, such as MX and A, but it does not provide unneeded records, such as AAAA records. We respond to queries for this domain over UDP (we ran a TCP server that was regularly probed but very seldom asked a legitimate question; no, we will not transfer our zone to you; all legitimate TCP queries could have been answered in a single UDP packet). Finally, we are authoritative for this domain, and will answer all queries for this domain, but will rudely drop queries for other domains.
