We recently upgraded our Rootserver from Ubuntu 12.10 to Ubuntu 13.04. We had the same set-up on Ubuntu 12.10 and a perfectly working configuration of Postfix + Dovecot as Mailserver. After doing a clean install of Ubuntu 13.04 we initially tried to do the same setup (installed all packages well that have been set-up on Ubuntu 12.10 previously) and we tried to use the service-configurations we used successfully on Ubuntu 12.04 for Postfix and Dovecot. This won't work. Then we re-tried the set-up for Postfix + Dovecot after removing/reinstalling the packages using aptitude and tried to do the setup using IspConfig (we also used it on Ubuntu 12 and as well on Ubuntu 13). But this also fails. The main problem is that we don't find a working set-up for Dovecot to provide a working Imap/Pop3-Daemon. With all configurations we tried Dovecot is starting up. But we have a bunch of errors/warnings in Syslog. The main-problem is that we have either a reachable imap/pop3, but our Mailbox-Namespace is ignored (only Inbox working, but Sub-Folders are ignored). Other configurations we tested as well result in a non-reachable pop3/imap (daemon does not appear to provide the listening ports). Does anyone have a clue what is going wrong here? I feel like Dovecot isn't able to be set-up in the given version on Ubuntu 13 with this set-up? We are afraid of having to downgrade again to Ubuntu 12 (as the Server is already Hosting Websites). Our Dovecot-Namespace (Mailbox Directory Namespace) looks like this: Code: namespace { # Namespace type: private, shared or public type = private # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. # The default however depends on the underlying mail storage format. separator = / # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #- prefix = # Physical location of the mailbox. This is in same format as # mail_location, which is also the default for it. # location = maildir:/var/vmail/%d/Maildir/%n:LAYOUT=fs location = maildir:/var/vmail/%d/%n/Maildir/:LAYOUT=fs # There can be only one INBOX, and this setting defines which namespace # has it. inbox = yes # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension. You'll most likely also want to set list=no. This is mostly # useful when converting from another server with different namespaces which # you want to deprecate but still keep working. For example you can create # hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/". hidden = no # Show the mailboxes under this namespace with LIST command. This makes the # namespace visible for clients that don't support NAMESPACE extension. # "children" value lists child mailboxes, but hides the namespace prefix. #list = children list = yes # Namespace handles its own subscriptions. If set to "no", the parent # namespace handles them (empty prefix should always have this as "yes") subscriptions = yes } In the Filesystem it looks as follows (currently provided by our Mailbox-Backup of the previous Ubuntu 12 backup): Code: /var/vmail/[DOMAIN]/[MAIL]/Maildir/ Within Maildir it looks like this: .Drafts/ [...] INBOX/ AnyFolderInInbox/ MyCustomFolder/ Dovecot setup is
