All the advice from other messages stands. Each package has its
benefits. Everbody knows and supports sendmail, but it's annoying to
configure. Postfix is great, easy to configure, and now with "milter"
support can do almost anything that Sendmail can. Smail and Exim users
swear by their products, and I'm sure they're great (though I've never
used either). Zmailer scales beautifully, though if you actually have
enough traffic to take advantage of its scaling, you should buy another
five mail servers.
As for the best log analysis tool ... it's not free, but I absolutely
adore Sawmill (http://www.sawmill.net/). It will support any and all
log formats -- I currently use it with both Sendmail and Postfix logs.
Highly recommended. And not very expensive.

Grep is your friend. Innovative use of grep, even. And if you use
sendmail, here's a tool I wrote many many years ago that's had regular
use over the years: http://www.it.ca/~paul/mailqgrep
I haven't yet adapted it to Postfix logs. Trickier to parse.

Yup. The most detailed view of your log data is a direct one that you
can get using grep. I don't know those other packages, but I do love
Sawmill's web UI.
