How can I just search the local_domains list? I've looked at the various
lookup types but don't see any way to lookup something from the named list
and have it return a clean domain name that I can reference in $domain_data
I've got quite a few routers that are using 'domains =
lsearch,ret=key;/domains/domains.dat' which I assume Exim really is opening
that file and searching every time.
Can I make it more efficient by using the named list?
