OK - here's some more details about the "Main Domain" concept.

Some domains are 2 part like:

yahoo.com
exim.org

some are 3 part:

yahoo.co.uk
yahoo.com.au

The idea is to figure out what the rules are to see if you need to grab
2 or three parts. The following code is a crude attempt to demonstrate
this concept but if it's doable it would be better if it were hard coded
in Exim.

warn    message = X-Maindomain: \
${if match{XX${extract{-2}{.}{${domain:$h_From:}}}XX}{XX(co|com)XX}\
{${extract{-3}{.}{${domain:$h_From:}}}.${extract{-2}{.}{${domain:$h_From:}}}.${extract{-1}{.}{${domain:$h_From:}}}}\
{${extract{-2}{.}{${domain:$h_From:}}}.${extract{-1}{.}{${domain:$h_From:}}}}\
}
