exactly and I am presently using fail2ban to block:

  [postfix-tcpwrapper]
  
  enabled  = true
  filter   = postfix
  action   = hostsdeny[file=/etc/hosts.deny]
             mail[name=Postfix, [EMAIL PROTECTED]
  logpath  = /var/log/mail
  bantime  = 300

which places 554 rejection ip into /etc/hosts.deny, but the firewall
action denying rogue ssh attempts is cleaner, requires less resources
and sees the ip sooner.

is this correct:
FW_SERVICES_ACCEPT_EXT="0/0,tcp,25,,hitcount=3,blockseconds=120
