Define POP3 server by email

Given an emailof the form [email protected].
You need to define an incoming mail server (address and port) to read the email. It is desirable to specify a username.

Example:
For [email protected]should return pop.mail.ru:110 username:name
For [email protected]should return mail.ekotek.info:110 username name+ekotek.info

You don’t have to check for the latter. Brought only to show that the names for postal addresses are taken not before the @ symbol. And I doubt that this is even possible for the latter (name definition).

BUT: The Gmail service defines the domain nicely.

I would venture to suggest that there is a search of common names (pop, pop3, mail, relay, etc.) with a check on port 110.
