I have been investigating this for a long time but I'm not able to find a solution:I have an up&running mail server with Postfix and Courier in an Ubuntu Server. I'm using PAM users with a Maildir mailboxes structure. All this is working in the same hard disk.The problem is that I need to install/configure users mailboxes in a bigger disk unit already configured in my server (sda is where ALL is installed and sdb is where I want to setup the users mailboxes).Is not needed to migrate actual mailboxes.I,m not able to say to Courier to look at the users Maildir in the sdb drive when the mail client check the mailbox.Any help will be very appreciated.Thank you all!.
