IMAP - retrieve mail by Yahoo X-YMailISG

Appears for all incoming Yahoo mail, X-YMailISG is an incoming message ID mail can be retrieved by. I'm wondering if this is possible in IMAP or if this field is used for something else entirely?

From RFC 3501, section 6.4.4, you could use SEARCH or UID SEARCH with the HEADER qualifier to look look for the identifier for that message.

Quoted:

HEADER <field-name> <string>
         Messages that have a header with the specified field-name (as
         defined in [RFC-2822]) and that contains the specified string
         in the text of the header (what comes after the colon).  If the
         string to search is zero-length, this matches all messages that
         have a header line with the specified field-name regardless of
         the contents.
