Hi, I'm in front of a mailserver migration with Zarafa and Postfix. We want to migrate as smooth as possible, offcourse, and I was thinking about dual email delivery. This means that all incoming email will still go through the old mailserver, record the message in the mysql database and then "relay" the mail to the new mailserver. On the new mailserver the email is recorded in the new mysql-database so both mysql databses are in "sync".
I was thinking about transport-maps, but this only "relay" the message to the new server. It will not record the message in Mysql first on the old server, before it will relay it to the new mailserver. This setup would be nice for migrating group by group in our organisation and have a full rollback in case something goes wrong. I such a setup possible? Kind regards, Roland
