Changes:

- Remove atd from Service Check in Server Check Report

- Ensure all DNS traffic between non-local IP addresses in /etc/resolv.conf is allowed through the firewall when DNS_STRICT_NS is not enabled

- Added exim to example script pt_deleted_action.pl

- Added /var/log/cxswatch.log to csf.logfiles for new installations

- Added new option LF_ALERT_SMTP which allows lfd to be configured to send alert emails via SMTP instead of through the SENDMAIL binary. LF_ALERT_SMTP needs to be set to the name or IP address of the SMTP server to use this feature

- Added new option CC_DROP_CIDR. Set this option to a valid CIDR to ignore CIDR blocks smaller than this value when implementing CC_DENY/CC_ALLOW/CC_ALLOW_FILTER. This can help reduce the number of CC entries and may improve iptables throughput

- Improved installation procedure for checking required perl modules
