Complexities of e-mail validation logic

That causes weird behaviour in places, where they assume the bit before the @ is a "username".

I've been using this strategy for years and have not encountered that issue before. That would mean the part before the @ would have to be unique across all domains. That doesn't make any sense. You couldn't have [email protected] and [email protected] registered for example.

Or [email protected] and [email protected] couldn't both be registered. This scheme is so obviously flawed I can't imagine it's widely implemented.

I've been using an own domain with wildcard emails for many years now. I'm yet to encounter a single scenario of inferred names.
