I just upgraded a server from Courier-IMAP to Dovecot, and I'm seeing
some odd behavior. It's probably the result of something I did wrong
in my configuration, and I'm hoping someone will let me know the easy
fix for it.

I have rules set up in Apple Mail to move and copy messages to
different folders, some of which are IMAP folders, others on my own
system. With Courier-IMAP, the messages would get moved without a
problem. With dovecot, that's not happening.

Here's my dovecot config. I've tried changing
maildir_copy_with_hardlinks and maildir_copy_preserve_filename to
"no", but that didn't seem to help.

# 1.0.10: /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes namespace: type: private prefix: INBOX. inbox: yes auth default: mechanisms: plain login digest-md5 cram-md5 username_chars:
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir

I haven't tried logging the IMAP session yet, but I can turn off SSL,
fire up Wireshark and monitor the session if necessary.

Is this a known problem? I'm able to move messages between folders
manually, but when Apple Mail moves the new messages it doesn't work.
