Perhaps: ${if match{$sender_host_name}{\N(?:^|\.)\N${sg{$acl_m55}{\N\.\N}{\N\\.\N}}\N$\N}} is what you want? It used to be that match_domain gave you what you wanted, but this proved to be too vulnerable to insecure configurations being created, so we stopped expanding the right-hand-side. :-( The above ${sg...} assumes that the results of the database lookup can only match legitimate Internet domain-names, so the "." is the only regexp special character that can occur. > Is it possible to achieve this kind of behavior with something like this (not > working as I want - yields nothing): > warn condition = ${if match{$$sender_host_name}{\N\.$acl_m55$\N}{1}} The $sender_host_name should not have $$ doubled, you're causing an expansion failure there. Is the above what you wanted, or have I misunderstood?
