changing configuration

[notze]

i installed ispconfig on 3 debian-server

A <-- dns server, mail server, db server, webserver
B <-- redundant server from A
C <-- only webserver

now i want to move the mail from A and B to C or D(new one).

how can i disable the mailing service on A & B ?

Any ideas would be great !! thx!

First change all MX records and create transports on A and B so that mails that arrive on these servers are forwarded to C (see

man 5 transport

). After a week or so (after your DNS changes have propagated) you can switch off Postfix and Dovecot/Courier on A and B.

to copy the maildirs, can i just rsync them?

and is there a way to export import the mailsettings?

the rsync of the cur and new folders works like a charm.

just the import export of the entries in ispconfig is unclear
