hi ershad here,
running a windows 2003 server as a domain controller for 100 machine with XP as clients . i have 150 users working . have a redhat enterprise linux 5 working as file server ( samba, squid, internet connection sharing). redhat is also a member of the domain and working fine .samba is working with AD domain authentication . i want to implement sendmail as a mail server for my environment which should be working for all domain users (receive and send mails to all other domain users ) . what are the steps and configurations .

thanks ....

Ershad,

Do you mean you want the 2003 server to use RHEL5 as a smarthost? Or do you mean to use it as an SMTP, POP3, IMAP mail server?

Carl

thanks in adv
i want my linux server should work as mail server(imap,pop3,smtp)in my domain . no exchange server exists . i dont want also .

note: All i want is a sendmail server working for the AD domain . and all users should be able to send and receive mail with there AD authentication

Ershad,

In that case, take a look at using postfix for smtp and dovecot for imap & pop3. There are lots of howtos out there and postfix is much simpler to setup than sendmail.

Carl.
