So "verify = sender" That's going to activate the routers, if it hits a "dnslookup" router that is enabled for verify then yes there will be a DNS lookup for MX (shortcut-or A) records, they will be resolved to A records (if needed) and compared agaisnt any "ignore_target_hosts" on the router. The succesful router will drop this (filtered) list of IP addresses into some variable. $sender_address_data perhaps or it might be an internal variable that is hidden from you. certainly it couldn't hurt to try logwrite = sender verify ($sender_address) = $sender_address_data in your ACL code. -- Jasen. 🇺🇦 Слава Україні -- ## 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/
