mail software for freebsd

[vaida bogdan]

Hy, I woule like to know which mail setup that has the following
characteristics you use for primary mail servers:
       - fast and reliable delivery
       - anti spam/phishing/virii filterring

I would like to reduce the number of packages used in my current
configuration or possibly change it as I have a hard time debugging
problems.
  - postfix+qmail maildir
  - courier imap
  - razor agents
  - procmail
  - spamassassin
  - amavis
  - clamav
  - cyrus sasl2

Thanks,
  Bogdan
