I believe it actually depends on "postfix | mail-transport-agent" - which
means any MTA will do, but if you don't have one it'll install postfix.

They should be.  I like to use "masqmail" - much simpler than postfix, and
it expects intermittent connections, so always resends mail as soon as it
connects.  iirc, postfix will retry on a schedule - and you may not be
connected at the next retry time, either.

It certainly could.  Most MTAs will have the "mailq" command, to tell you
what's in the queue.
