I have a box that is 90% ISPConfig managed users, the rest are added by hand. After I add a user and create a maildir for them with maildirmake.courier, then chown -R to the user, incoming mail is stored in an mbox rather than the maildir. Where can I configure procmail to drop to a maildir per user? Thanks in advance, Peter.
Procmail is configured per user. Execute the command "ls -la" in a user home directory managed by ISPConfig and you see the procmail recipes involved in storing emails in ISPConfig. But postfix is able to store emails in maildir without procmail. Do you have this line in your postfix main.cf file? home_mailbox = Maildir/
