Its not useful to me, and possibly just as confusing to others, for you
to abandon English and express your thoughts in Pearl. I have my still
unread Big Black Book from 1999 which I will peruse to understand what
'm' means.

I have changed the test to this, which I think will be more effective at
detecting the use of 'mail server' connections having 'ADSL' in their
host names.

deny    message       = [C06.5]  Msg6 Msg2
        hosts         = ^.*[a][-_.][d][-_.][s][-_.][l]* :
^.*[a][d][s][l]*
