I have setup a virtual mail server as described in http://howtoforge.net/fedora_virtual_postfix_mysql_quota_courier. But I encounter a problem with adding and deleting of virtual users. The system doesn't add or delete the mailboxes in /home/vmail/domain. The virtual domains aren't added or deleted as well. What's wrong? The server is operating normal. I have one domain with 12 mailboxes running now. But the amount of domains and mailboxes will be extended within a few months. Who can help me?
