Qmail to Zimbra

[abhiz]

HI One week ago I shifted from Qmail to Zimbra Open Source Edition.Earlier my Qmail server was hving 2 domains abc.com and xyz.com ...but I have not shutdown the services on Qmail server that server is as it is ..what I did just increase the MX record for my Qmail server.Most of the Emails are receiving by Zimbra Server but some of the emails are receiving by Qmail.

It seems that those emails with unknown host are not receiving by zimbra.I have already uncheck the unknoewn host option in zimbra administration knosole.
Can any one help me out .Where I am wrong....

Thanks
Abhiz

If you wish to run two mail server with the same domains you should have a read of the Split Domain set-up.

I dont want secondary server should receive a single email on the same time I dont want to shut it off...

It would help if you posted your MX record information and the following aswell from your ZCS server

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes

No I want all the emails should be handle by my ZIMBRA server ...No email should get rejected from zimbra server.
