In the message filter match criteria ("contains", "begins with", etc) an option
to  treat the filter string as an extended regular expression would be helpful.
Criteria such as "contains regex" and "doesn't contain regex" would be good.
What I would like to be able to do is to filter on things like the top level
fragment of IP addresses. For instance:

  "{128|236}[.][0-9]{1,3}[.][0-9]{1,3}[.][0-9]{1,3}"

The closest that I can get with the current filters are patterns like "contains"
"128." but filter terms like this can match much more than they are intended to.
