Use a regexp or PCRE map if you want a 'default' action. The proper
syntax would be:
/./ ACTION
Remember that the order matters in regexp tables, so this must come
last.

The correct syntax for the FILTER action (example for a regexp table):
/d2\.tld$/ FILTER smtp:myfilter
Note whitespace, not a ":" following the FILTER keyword. I failed to
catch this error on a previous example I posted.
