Relaying all mail thru Qmail to new server

Hi all.

We have old hardware (Qmail & vpopmail) that is hosting about 2000
boxes which we are moving to new server. There sure are some customers
that has their own dns servers pointing MX to this old server, so we
need to relay all incoming mails to new server after switch-over.

Is this correct way to do it with Qmail ? :

Add file /var/qmail/control/smtproutes with server name
:our.newserver.com

Remove all domains from /var/qmail/control/virtualdomains

svc -d /service/smtpd
svc -u /service/smtpd

Then follow logs what email is still coming in. We have seperate
'front-end' servers which filters spam and transport it to mailserver,
so don't need to wait for dns TTL's to refresh.

If im missing something here or if there are smarter ways to do this,
please share ideas :)

Regards,
Kimmo Hedman

This step isn't necessary. All that is necessary is:

svc -h /service/qmail-send

(or whatever your equivalent is for qmail-send).

Other than that, it seems like a sensible approach. Basically you'll
leave rcpthosts intact indicating that your qmail server will still
accept RCPTs for those domains that point to it. Then because there are
no locals/virtualdomains for those domains they will simply be relayed
to their final destination, which you have redirected to the new server.

Unless you're using a insensibly modified qmail, the only thing that is
relevant for delivering emails in qmail are qmail configuration files.
vpopmail database information only pertains to accounts that receive
email, now how qmail decides to route the messages.
