While that's certainly a subset, there are a whole lot of other
mailers to choose from on Unix. Alphabetically... exim, postfix, qmail,
smail, zmailer... To name a few.

Type any of the above names into Google.com, and hit "I'm feeling lucky".
Most of the sites are mailer.org, except for smail, which is currently
ftp://ftp.planix.com/pub/Smail/

None of those have to do with the MTA. #1 is a web based MUA, such as IMP
http://horde.org/imp/ - though that's just one example.

#2 - I haven't seen a generic tool for - all custom written ones. Most
MTAs can support ~/.forward files, so it's not too hard to do.

By #3 - do you mean RAID, for disk protection, or do you mean complete
host failure? You can certainly have mail copied to a second server for
redundancy, but you'll need to write some code to keep mailboxes in sync,
etc.

That's not the MTA either - that's a pop server. There are many in
pkgsrc/mail

What's the relation of your questions to NetBSD?
