My 2 CDN cents (almost worth as much as 2 US cents these days!):
I inherited our sendmail setup 5-6 years ago and almost every time I
tried to modify something I had to spend lots of time reading the 900+
pages sendmail bat book or Googling around. Sendmail's website is a
piece of crap where you almost never find what you are looking for. As
for Google results, most of the time they don't apply to our setup or
sendmail version.
I tried to switch to Postfix but had to go back to sendmail because the
LDAP schema we use for sendmail cannot be accessed in Postfix... This
was really unfortunate because my limited Postfix experience convinced
me that Postfix is way more easy to configure than sendmail's arcane MC
or CF files.
Nonetheless I think that sendmail is a secure MTA but it is really a
PITA to configure!
