The REGEX functionality allows you to whitelist or blacklist messages based on
pattern matching the message body itself (not the RIC).

The options for this are:


WhitelistRegexfile=
BlacklistRegexfile=

REGEXs are placed in the the respective textfile, one per line. These need to
be a full match, i.e. they need to match the entire message, begining with ^
and ending with $. 

For example:

^NAGIOS.*$ - matches all Nagios alerts

^(G|M|2).+$ - Matches messages with the first character as a G.M or 2 - i.e.
match all UK callsigns.
