Hello all,

I'm migrating to Dovecot from Courier-IMAP. I use Postfix with Maildir for delivery.

When I use Dovecot as the IMAP server all of my folders are missing, the only thing that remains is the Inbox folder.

Has anyone else experienced this issue? I have enclosed my configuration.

Thanks,

Chris

This is always set with mbox mailboxes, and # also default with Maildir. # # Different IMAP clients work in different ways, that's why Dovecot by default # only caches MessagePart which speeds up most operations.

Normally you should leave this alone, unless you know # what most of your IMAP clients are. Caching more fields than needed makes # the index files larger and generate useless I/O. # # With maildir there's one extra optimization - if nothing is cached, indexing # the maildir becomes much faster since it's not opening any of the mail files. # This could be useful if your IMAP clients access only new mails.

# Use mmap() instead of read() to read mail files. read() seems to be a bit # faster with my Linux/x86 and it's better with NFS, so that's the default. #mail_read_mmaped = no

# Copy mail to another folders using hard links. This is much faster than # actually copying the file. This is problematic only if something modifies # the mail in one folder but doesn't want it modified in the others. I don't # know any MUA which would modify mail files directly.

Works with NFS too if lockd is used. # flock : May not exist in all systems. Doesn't work with NFS. # # You can use both fcntl and flock too; if you do the order they're declared # with is important to avoid deadlocks if other MTAs/MUAs are using both fcntl # and flock. Some operating systems don't allow using both of them # simultaneously, eg. BSDs. If dotlock is used, it's always created first. #mbox_locks = dotlock fcntl

# Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. #mbox_read_dotlock = no
