Hello all,We want to migrate a customer (with 50 domains and 600 mailboxes) to DBMail. This is a good opportunity to cleanup their mailbox mess, so we won't import existing mailboxes but start with a fresh new DBMail. To allow them to take the time they need to think about aliases, mailboxes, etc we would like to create a setup like this:
1. New Server (Postfix + DBMail) 2. Old Server (Postfix + MySQL + Maildir) We would like this setup to behave like this:1. The new server receives the e-mail, tries to deliver it to DBMail, if it fails (because no aliases exist for this message yet)
2. The old server tries to deliver the e-mail. I've tried to:1. Setup the new server as primary MX and the old server as secondary MX, but that didn't work (the new server bounces the mail if DBMail can't find an alias/user). 2. Setup the old server as fallback_transport in postfix main.cf. Doesn't work, a bounce message is sent anyway.
Questions:* Is there a way to stop DBMail from bouncing a message if it cannot be delivered, but reject it instead? Maybe a rejected message will be given to the fallback_transport?
* Do you know other solutions? Thanks! Bert Slagter Procurios Webdevelopment
