Another possible explanation is that exim is the default MTA offered
with Debian, which is itself fairly popular around SVLUG.    This is of
course somewhat chicken-and-egg:  exim is popular because it's offered
on Debian, but it's the Debian default because the conifguration and
maintenance are sane.

Other relative merits:

  - It's FSF Free Software / OSI Open Source Certified (as opposed to

  - As noted, it's got a better security reputation (noting that
    Sendmail's been pretty good since the mid/late 90s) and
    configurability than Sendmail.

  - There are many useful plugins and modules you can add to exim.  It
    offers a great deal of flexibility, most of which can be added
    fairly painlessly (anyone who's tried gathering, building, patching,
    installing, and configuring qmail add-ons can appreciate this).

  - It's not the fastest, safest, most configureable, what have you,
    MTA.  However, it *does* balance a bunch of competing interests
    pretty well.  
Compare it to postfix and courier as other midweight alternatives.
Marc's got a good MTA list which may or may not be an LJ article by now.
