About the Email Address Parser
Everything an address is made of, pulled apart and labelled: the display name if there is one, the local part, the sub-address tag, the mailbox the tag resolves to, the full domain, the subdomain, the registrable part and the top-level domain.
It reads the shapes addresses actually arrive in, not just the bare form — a name in angle brackets, a quoted display name, a mailto: URL, a trailing comma from a header that was split by hand, and the invisible characters a copy from a PDF leaves behind.
Useful when you are writing the import and need to know what you are getting, and useful on its own when you just want the domain out of a hundred addresses.

Frequently asked questions
Everything before the final @ sign. It identifies the mailbox within the domain, and the receiving server decides what it means — including whether it is case-sensitive, which it technically is but almost never is in practice.
The part after a plus sign at most providers, or a hyphen at Yahoo. ada+news@gmail.com delivers to ada@gmail.com with a label attached, which is why it is useful for tracking where an address was given out.
Yes. The display name is separated out and reported on its own, with or without surrounding quotes.
