On search, UID range sends always the last mail about node-imap

Actually, scratch that. The RFC states this is expected behavior:

Excerpt from section 6.4.8:

           Also note that a UID range of 559:* always includes the
           UID of the last message in the mailbox, even if 559 is
           higher than any assigned UID value.  This is because the
           contents of a range are independent of the order of the
           range endpoints.  Thus, any UID range with * as one of
           the endpoints indicates at least one message (the
           message with the highest numbered UID), unless the
           mailbox is empty.

Can you post debug output generated by setting the debug property of your connection options to console.log? Censor your username and password.

Also, the literal IMAP command string, "SEARCH UID 101:*" will return sequence numbers, not UIDs.

Thanks.
