No, Biff informs the system whether you want to be notified when mail arrives during the current terminal session.

I.e.,

    NAME
       biff -- be notified if mail arrives and who it is from
    
    […]
    
    HISTORY
       The biff command appeared in 4.0BSD.  It was named  after  the  dog  of
       Heidi Stettner. He died in August 1993, at 15.

    Eric Cooper, a student contemporary to Foderero and 
    Stettner, reports that the dog would bark at the mail 
    carrier,[4][5] making it a natural choice for the name 
    of a mail notification system. Stettner herself 
    contradicts this.[3][6]

    From the excellent "A Quarter Century of UNIX" (by the late Peter H. Salus):

    Heidi would bring her dog with her to class and to her office. He was a very friendly dog, and a lot of the students enjoyed throwing a ball for him down the corridor to fetch. He even had his picture on the bulletin board with the graduate students: the legend read that he was working on his Ph.Dog. John decided to name the program after the dog: Biff. According to Heidi, John and Bill Joy then spent a lot of time trying to compose an explanation for biff - they came up with "Be notified if mail arrived." Biff, who died in August 1993, at 15, once got a B in a compiler class. According to Heidi, the story of Biff barking at the mailman is a scurrilous canard.

    One of my favourite bits of trivia from that excellent book, but hardly anyone I bump into these days knows anything about that kind of multi-user Unix experience/environment these days. I barely caught any of it myself.

Yeah the name collision is unfortunate, but probably fine. The name Biff was just too good to pass up.

The name comes from the fact that Biff is a character in Back to the Future, and it rhymes with Jiff[1]. Jiff is the datetime library that Biff uses.

All short names, that is, pronounceable strings of 4 or maybe even 5 letters are already taken. Some of them taken many times over.

I think fewer people now care about mail notifications in a terminal session than about wrangling datetimes on the command line.

Yes I'm sure root is anxious to read all the mail in their local mailbox

    Sending mail to root@<whatever> really did use to be a pretty reliable way of getting somebody useful's attention - the early-to-mid 90s equivalent of making a "Can someone from Google please unlock my account?" post on HN.

      Under Debian/Ubuntu, when Postfix is installed, part of the standard list of questions that dpkg-reconfigure asks you is how you want mail flow to work: you can give it a central smarthost. So any local mail gets sent on, and on the central mail hub you can tell it to send root@ to someplace useful:
