+==== Deduplication ====
+Sometimes, root cause of replication troubles seem to be duplicated emails. Those might be cleaned up in mailboxes //INBOX// and //Spam// for account //user@example.com// by
+<code bash deduplicate.sh>
+while doveadm deduplicate -u user@example.com mailbox INBOX OR mailbox Spam
+do
+  fgrep -c Message-ID: example.com/user/mail/Spam xid.at/xen/mail/INBOX
+  echo "++++ `date` +++++"
+done
+</code>
+This will run forever ans should be stopped when numbers do not change any more.
