dear liz
use masquerading feature in sendmail.mc and set masquerade domains or host
names as followings
MASQUERADE_AS(`csr.com')dnl
FEATURE(masquerade_envelope)dnl
MASQUERADE_DOMAIN(localhost)dnl
MASQUERADE_DOMAIN(localhost.localdomain)dnl
then in /etc/mail directory
simply type "make"
this result in all dbs hashed and sendmail.cf produced
in the last step restart sendmail then make these tests
note that someone, someone at localhost, someone at localhost.localdomain turned into
masquerade domain someone at itu.edu.tr
[root at localhost mail]# sendmail -bt

Enter <ruleset> <address>
