Sendmail issue

Hello all,

I want my sendmail which alreday forwards all emails to a specific DNS and domain name to be changed and all emails will be forward to a different domain name but the previous one will not be affected.

I do not know if I present my problem correctly but I am new on sendmail.

Of course new MX records will be send to me for the new changes.

Can anyone help of how to do that?

thanks in advance
Mimas

You can do that but what about the DNS propagation time ...?
