IMAP Search Unread Mails by UID

Mar 13, 2013 at 8:03 PM
I did not found a Search function for IMAP Command UID SEARCH UNSEEN.
Is there such function or it is missing? There are many UID functions, but not one to fire a command like above.

Believe me, I found some servers where SEARCH returns Bad Command.

As an alternative, I´m using Imap4Client.Command("uid search unseen")
