Security:

Sendmail has a long history of security problems.  In its defense, it's been
beaten to death the last decade and had not had as many security problems.
Also, I think OpenBSD uses sendmail by default.

Postfix & Qmail have been designed from the beginning to be secure. Sendmail
has had it added.  It's very hard to add after the fact.

Multiple layers for security in depth.  Run qmail outside the firewall,
postfix inside and sendmail/exchange on local boxes.

Simplicity:

Simpler configuration syntax.  Fewer tools needed.  Fewer transports
supported (UUCP not needed usually).  Smaller footprint.  Faster operation?

Smaller code/fewer features also mean fewer places for exploits to hide.
Easier to code review.
