I just set up my server with MySQL support for authentication/authorization
compatible with Postfix Admin.
Initially, I was getting the "Relative home directory paths not supported"
message, and it's easy to see why - Postfix Admin stores the maildir as
"$domain/$userpart@$domain".
But the directories in 10-mail.conf are set as
mail_location = maildir:/home/mailboxes/%d/%u
mail_home = maildir:/home/mailboxes/%d/%u
...and the user_query has been revised to:
user_query = SELECT concat('/home/mailboxes/', maildir) as full_maildir
FROM mailbox WHERE username = '%u';
...so how are any of these relative paths?
