A valid email domain is a domain that can be resolved (via MX and/or A and AAAA) records to a working mail exchanger for that domain. Defining "invalid" is apparently subjective, if your request is indicative... In my view, the only way to tell that a domain is "invalid" is if it doesn't resolve or if DNS leads one to a bogus IP address for an MX: e.g. RFC1918, loopback, test-net, etc. > Examples of such would be typo domains One man's "typo domain" is another man's "I had this name first!" domain. > and/or domains that accept all local-part addresses There is NOTHING objectively "invalid" about that. It's not something most mail systems should do for most domains in the modern world but I know many people who are still using "catchall" domains happily. > such as gmai.com, gmail.co, googlemai.com, or proton.com.

Given that you seem to want a list of domains that fit your extremely personal concept of "invalidity" I do not expect that anyone has any list that you would find useful. If you invent a set of criteria for "invalid" domains from thin air, you will likely need to identify such domains yourself. -- Bill Cole [email protected] or [email protected] (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Not Currently Available For Hire _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
