Hi I try to setup a mail server which fetches mails from some pop accounts and presents them through imap (with dovecot) to my local network. I get the mails with getmail at this works as it should. To use dovecot as a pop3 and imap server works too. Now I am trying to setup multiple mailboxes which then should be presented to the user as different folders. I think I have to use namespaces for this (is this correct?) So I tried to configure two namespaces with the following statement. namespace private { separator = / inbox = yes prefix } namespace private { separator = / prefix = ns location = maildir:/data/server/mail/in/%u/ns } when i try to access the imap server with thunderbird I can receive mails for Inbox but when I want to subscripe an additional folder ns can be seen but is grayed out in thunderbird. To summarize this can anybody give me a hint or example how to configure multiple mailboxes which are located in different directories on the server. thx
