I think using example.com is a bit of a trick question. It is known as an example domain which is invalid for all purposes, except of course for serving as an example. :)

- wredcoll 1y agoI've actually been wondering for a while if example.com is a valid example email address.
- mdaniel 1y agoWell, "valid," yes, but "deliverable" thankfully, no $ dig MX example.com. ;; ANSWER SECTION: example.com. 3600 IN MX 0 . Almost certainly the same for its .org .net and .example friends. There were some other TLDs that were designed for use in documentation, but I don't have the RFC in front of me right now to cite them
- SoftTalker 1y agoSome of the other examples which are "technically valid but obsolete" I would consider safe to call invalid for practical purposes.
- samwho 1y agoYeah, I almost put a disclaimer at the end saying that while these examples are valid according to the spec, that has no bearing on whether they’re usable in practice. Email is the Wild West.
- olddustytrail 1y agoExactly. Not valid because it can't be routed.
- TMWNN 1y agoYes. If I'd known that other questions would also use example.com, I would have answered the first question correctly.
- paulnpace 1y agoAn explanation of the use of example.com would have informed users that addresses should be evaluated as such, otherwise, AFAICT, all of the examples provided are invalid.
