hi,

i had configured postfix mailserver in rhel4 update 4.
postfix-2.2.10-1.RHEL4.2
server hostname is experts.linux.com were i configured postfix smtp
and imap.
imap-2001a-18 is which i used.

i had configured squirrelmail in another machine where the hostname is
rules.linux.com
squirrelmail-1.4.6-7.el4

when i send any mail to smtp server(experts.linux.com) from
squirrelmail server(rules.linux.com) its working fine.
mails are delivering to the respective users.

my problem is i had to add multiple domains in smtp server.I had to
add these server in the main.cf file of experts.linux.com.so that when
i send mail to these domain users from squirrelmail (clients) it
should be delivered.

my task is i had send mail to radius.linux.com user from squirrelmail
(rules.linux.com).IS there any other way other than DNS and pointing
the other domain in relay host.
