Ruby/IMAP getting messages starting from the last saved mesage uid

I'm trying to get new messages starting from the last saved message id of a folder.

Here's my code so far:

self.imap_connection.examine(folder)
imap_query = "UID SEARCH #{last_uid}:*"
messages = self.imap_connection.search(imap_query)

The only response I'm getting from the IMAP server is: Error in IMAP command received by server.

So, does anyone know the correct "syntax" for the ruby imap library to get the uids ??

Regards, Alex

Getting all the messages after a certain last fetched UID works for me.

imap_connection.uid_search(["UID", "#{last_fetched_uid + 1}:#{MAX_UID}"])

The solution is getting all messages of a folder by it's uid and saving it's seqno(it's an imap field):

imap_connection.uid_search("ALL")

For getting new mails search using the last saved seqno:

imap_connection.uid_search("#{seqno.to_i}:*")

Searching via the last saved uid did not work for me so I used the last saved seqno and voila.
