Allow address.parse() to reject addresses with local hostnames

address.parse() currently accepts addresses with a single-part domain as used for a local mail host, e.g. bleah@example. I am currently working on a use case where we would only want to send to Internet addresses, like [e-mail] or [e-mail]. It would be useful to have an option to reject addresses with single-part domains.

It seems to be too use case specific to be included as a parser option. I can think of many similar specific use cases e.g.: do not allow domains of 3rd, 4th, Xth level; do not allow domains from specific top level domains; do not allow domains from a certain geo region… All that seems like a higher level of abstraction that lays out of the scope of the email address syntax parsing.

In your case the solution is as simple as:

addr = parse('bleah@example')
if addr and '.' in add.hostname:
    // bingo
else:
    // invalid address or local domain 

So I think it is out of the scope of Flanker and should not be implemented. @b0d0nne11 what do you think?

We don’t really want to go to the trouble of calling validate_address() when all we want is to check the form of the address, but thanks.
