Re: [exim] Help crafting a prefix-only hostname wildcard mat…

Bill,

Good, glad that works. Another way would be to use match...

/usr/local/exim/bin/exim -be
> ${if
match{:tom:dick:harry:}{:${extract{1}{.}{tom.foo.bar.com}}:}{true}{false}}
true
> ${if
match{:joe:dick:harry:}{:${extract{1}{.}{tom.foo.bar.com}}:}{true}{false}}
false
> ${if
match{:joe:tom:dick:harry:}{:${extract{1}{.}{tom.foo.bar.com}}:}{true}{false}}
true

Note the extra ':' at the front and end of the list. You can't just match
for 'foo', because 'foobar' would match, so you match for ':foo:', hence
the need to start and end with ':'.

Thanks, Dan,

I had either forgotten (or never known) that 'match_local_part' is not
just-and-only hard-wired to look at the string separated by a '@' from
<domain>.<tld>

Testing as:

condition = ${if match_local_part{${extract{1}{.}{$sender_host_name}}} \
              {<string(1)>:<string(n)>{true}{false}}

Which seems to be working as expected - and more effciently than an
external table search, as I am looking for only a very, very few strings
(just one at present..).

Regards,

Bill
