Extended LUSER_RELAY

Abstract

New way of getting the same results coming soon.

The document describes how to modify your sendmail configuration to allow extended LUSER_RELAY syntax in the following form:

DLmailer:host,domain

OR

DLhost,domain

It will cause unknown local user "xyz" to be relayed to "host" via "mailer" with address "xyz@domain"

Before applying the suggestion below read about FEATURE(`preserve_luser_host') introduced by sendmail 8.12 - it may be a good alternative.
