Non-existing/unknown addresses CAN be mapped by smtpd_sender_login_maps, as every map type has some form of wildcarding. An address which matches in the map is known, one which does not match in the map is unknown. Whether the address is non-existent (i.e. cannot be delivered to) is a different issue, and a non-existent address can be a 'known sender' in the context of smtpd_sender_login_maps. -- Bill Cole [email protected] or [email protected] (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Not Currently Available For Hire
