Be precise: you use unison to keep the directories that serve as mail
storage for some IMAP servers in sync. Your unison does not know that
there is IMAP involved.
Correct. Unison has no idea that it's synching maildirs.
cat inbox-imap17.prf
# Unison preferences file

# Roots of the synchronization
root = /home/tim/Maildir/INBOX
root = ssh://imap17//home/tim/Maildir/INBOX
#Name matches anything, including a directory name.
#Path matches anything but is anchored at the root
ignore = Name .lock
ignore = Name {dovecot.*}
ignore = Name {dovecot-*}
ignore = Name {tmp/*}

I've never 'tried' to break it by, for example, performing imap things
on the same email on two servers at once but my guess is I'd end up with
a duplicated email. It's possible I'd get a synch conflict but I've not
had one yet. And I do occasionally use imap on more than one server at
once.
But I'd assume dropping files into the maildir with non-conflicting
names - there might be restricions on how they should be named - would
'just work' at least with dovecot.
