I have a scenario.
I have a domain abc.com as my organizations mail server in a Sun Solaris using sendmail.
Now I created a Zcs server where I want few of my users to migrate.
the existing servers domain is : abc.com
The mail server is : mail.abc.com
The new zcs server is : email.abc.com
in new server user address are firstname.lastname@example.org so is in the previous server.
Now we have a barracuda protection so the primary MX is barracuda from where mails are pushed to old server.
Now I relayed SMTP through mail.abc.com
so when i send a mail to any one of @abc.com they receives it in old server mail box and so is the box i want in new server and can send mail to any other place using @abc.com.
How can I get specific users mail directed to my new Zcs servers mail where i created that box?
exactly I am a part of abc.com and i need to use the new zcs server using @abc.com & send as @abc.com.
