'mail' was the default mail user agent on Unix afaik. Basically, it's the ed of MUA - you could use it on a typewriter without problem. Eventually 'mailx' came out, which was an improved version of it, which last I looked was what FreeBSD used for their /usr/bin/mail. A quick look on Google shows that nail is as OKO stated, mailx on steroids, or a "modern replacement for the ancient mailx" utility adding IMAP/SMTP support and what nots.


Personally I think a pure MUA that leaves everything but the most core elements of it to external programs is great design; but I find something that can at least send mail in isolation easier to work with, when hoping between different apps (mailx, mutt, kmail, thunderbird, webmails, etc).
