So I also need to put /var/qmail/queue in NFS?
Won't there be any problems with multiple daemons who are not in the
same memory space working on the same queue folder?

Hello!
I need to "move" my one email server to new ip address. I wouldn't
like to make something crazy like dual gateway routing to achieve this.
So actually I have this educational idea to test it out and set up 2
qmailtoaster boxes to back each other up (replication) during the ip
changing phase.
What's roughly the idea how to have 2 identical qmailtoaster boxes
(so if I change the ip address on the DNS it will transparently
change over to new server with zero downtime to customers)?
I can have common mysql server for those 2 boxes, this is not a
problem (and i know how to set up mysql replication if i would ever
need to have separate mysql servers for additional security).
But will it work if I just keep db in sync and use NFS or glusterfs
to keep the same filesystem across the toasters (/home/vpopmail,
/etc/tcprules.d?)?
Is it correct that i need to have some files in sync from /var/qmail/?
Am I on the right track with my ideas at all?
You can use NFS as the backend, but you will need to only network some
of the config files.
I just did a video series on how to build a replicating Qmailtoaster
server over at http://video.qmailtoaster.com
Not exactly the same setup as you're attempting to do now, but the end
result is the same. I will eventually do a video on a setup more like
you're looking for in the future.
