I wonder if there any plans of extending exim file lookup
methods to include NIS/NIS+ searches. On big sites (>10,000 users)
distributed mail-related information usually spans more than
one host, making dbm diles inadequate, let alone plain text.
Something like:
local_domains = \
lsearch;/etc/exim/strict-domains:\
nisplus;domains.mail.local.org_dir
and
${lookup {$domain:type} nisplus {domains.mail.local.org_dir} {$value}
