Hello, in installed postfix with saslauth and courier-imap on my server to learn how to setup a mailserver. Postfix uses virtual accounts and reads all information from a database where every user account holds a 'home' and a 'maildir' field beside other required account information. For the 'maildir' field i initially used the value Code: example.com/username/ This resulted in all mail delivered in mbox format. In the next step i changed this field to Code: example.com/username/Maildir/ The skeleton for this field was stored in /etc/skel and had the qmail structure Code: Maildir/ cur new tmp This resulted in all mail delivered into the 'new' folder. All mail was sent from the terminal for testing. At this point i began to involve Mozilla Thunderbird to send and retrieve all mail. Connecting to the imap and smtp server works. I can send mail, but i cannot fetch it. The client connects and then immediately disconnects. I watch this process from the terminal via Code: tail -f /path/to/log/mail.log Since i don't receive any errors i suppose the problem to be within the folder structure. I searched the web, read several tutorials, but cannot get it to work. I read about an INBOX folder being required and the folders .Sent, .Junk, .Trash and so on. But it is nowhere clearly stated, which of them MUST exist and in what kind they relate to the INBOX folder. So i tried several ways. Code: example.com/username/Maildir/ INBOX cur new tmp cur new tmp Code: example.com/username/Maildir/ .Junk cur new tmp .Sent cur new tmp .Trash cur new tmp INBOX cur new tmp cur new tmp For the next try i changed the maildir field in the database to Code: example.com/username/INBOX/ Code: example.com/username/INBOX/ .Junk cur new tmp .Sent cur new tmp .Trash cur new tmp cur new tmp None of these works. Now my questions are: 1. How do the INBOX folder and all the dot-folders (.Junk, .Sent, .Trash ....) belong together? 2. How must the folder structure beginning from 'example.com/username/' look like? 3. Is is correct, that the whole path to the mailboxes beginning from the root is owned by the mail user vmail:vmail and chmodded 700? I wonder if the user trying to log in and read / write to the mailbox might have not enough rights. 4. Is there a way to track where the client is looking for the folders? Maybe it is looking at a completely different location.
