I am sorry that's the way you ended up feeling, but your first original
remains under-specified. Wietse's response re the internal form of
addresses, is correct, but quite likely entirely misleading, depending
on what you meant to ask, which remains rather unclear.
- The local(8) delivery agent in Postfix delivers email to bare address
localparts ignoring any domain part, and strips address extensions.
- The virtual(8) delivery agent treats the entire address as the mailbox
name, possibly stripping the address extension if no matchi is found
for that.
- Other delivery agents (via pipe(8)) can do whatever they see fit with
any part of the address.
Or perhaps you were asking about email coming in via SMTP, and what
address formats are expected there?
Without *context* your question was and remains much too vague. If your
question is broad enough, the answer is "read all the documentation" and
perhaps even the source code, because the question boils down to
something with roughly the specificity of "tell me, how does Postfix
work"?
