I prodded Ross a little bit and we (well him ;-) came up with a
suggested wording, I hope it is up to your standards.
Filter:
-For a `matches' test, after expansion of both strings, the second one
-is interpreted as a regular expression. Exim uses the PCRE regular
-expression library, which provides regular expressions that are
-compatible with Perl.
+A `matches' test expands both strings and interprets the second one as
+a regular expression. The match succeeds if the regular expression
+matches any part of the first string. Exim uses the Perl-compatible
+PCRE regular expression library.
We started on spec.txt to (with 11.5, the matches condition) but
now that I am going to send the mail I realize that there are
probably dozens of occurences. - I had not realized until now that
downhill.at.eu.org matched
domainlist local_domains = @:\N^downhill.a\N:localhost
Perhaps a big fat note in chapter 8?
