This raises a related question - how often will this query get executed? Is it once when the server is restarted, or each time a new client connection begins, or something else altogether?
Exim does run a cache for lookups, but it also re-execs at certain points in processing (to regain privs, needed eg. for delivery to file) and that loses the cache. So it's complicated. In general you can't rely on a given lookup being done only once, or on being done every time. In practice: within ACL processing, only the first one. Routers and transports, probably separate. https://exim.org/exim-html-current/doc/html/spec_html/ch-file_and_database_lookups.html#SECID64 -- Cheers, Jeremy -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
