Just a shot in the dark, but have you enabled the workarounds?
http://wiki2.dovecot.org/Clients
Some clients like, like Outlook, have known problems which dovecot can dance
around. in 20-imap.conf
# Workarounds for various client bugs:
# delay-newmail:
# Send EXISTS/RECENT new mail notifications only when replying to NOOP
# and CHECK commands. Some clients ignore them otherwise, for example OSX
# Mail (<v2.1). Outlook Express breaks more badly though, without this
it
# may show user "Message no longer in server" errors. Note that
OE6 still
# breaks even with this workaround if synchronization is set to
# "Headers Only".
# tb-extra-mailbox-sep:
# Thunderbird gets somehow confused with LAYOUT=fs (mbox and dbox) and
# adds extra '/' suffixes to mailbox names. This option causes
Dovecot to
# ignore the extra '/' instead of treating it as invalid mailbox
name.
# tb-lsub-flags:
# Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g. mbox).
# This makes Thunderbird realize they aren't selectable and show them
# greyed out, instead of only later giving "not selectable"
popup error.
#
# The list is space-separated.
