Looking for best practice guide for sendmail

I am looking to deploy sendmail and was wondering if there are any good
best-practice guides available. I surfed the subject for a few hours but
most of the information was rather dated.

Book recommendations are helpful too.

Essentially, I am looking for details on security, pros and cons of proxy
servers, connectivity with Winblows Exchange Server, antispam &
antivirus, SSL etc.

The compiling and configuration of sendmail is fairly well documented at
sendmail.org but a good reference on performance tuning would be handy as
well.
