Can anyone tell me how to reconfigure Sendmail to remove the "always_add_domain" feature. My RaQ3 is appending my server domain name to some incoming emails, particularly if the sender has mistyped their address.

e.g me@hotmail.com is fine when I reply, but me@htomial.ocm turns into me@htomial.ocm.myserverdomain.com

does anyone know how to do this?
