check host mailserver

[Nick Upson]

This doesn't work, I get "/etc/monit.d/mailserver:5: Error: syntax
error 'mailserver'"
the same syntax works fine for other machines so I assume the problem
is the machine name (? can someone confirm)

is there a workaround?

check host mailserver with address mailserver
  if failed icmp type echo count 3 with timeout 3 seconds for 3 cycles
then alert
