# positives on misconfigured MTAs.

#   filter = exim[mode=aggressive]
mode = normal

# The %(host_info) defination contains a <HOST> match
#
# SMTP protocol synchronization error \([^)]*\)  <- This needs to be non-greedy
# to void capture beyond ")" to avoid a DoS Injection vulnerabilty as input= is
# user injectable data.
