Restrict users of a domain to send/receive mail from one particular domain
Hi all,
I need some help of you all on sendmail. What I want to do is I like to restrict users of a particular domain say abc.com as they will only be able to send and receive mails from xyz.com and from no where else.
abc.com --> xyz.com
abc.com <-- xyz.com
How to do this in sendmail? SHould I use procmail or iptables or there is some other easy way around?
Waiting for you kind responses.
Thanks in advance.
