Sendmail configuration

[Hasan Aydin SASMAZ]

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
