Description

UIDL is a Boolean function used to retrieve the unique-id listing for one or all messages in the POP3 mailbox. 

When AMsgNum is specified, UIDL will request the UIDL for the specified message number. Otherwise, all message numbers in the mailbox are requested from the POP3 server. 

UIDL calls SendCmd with the POP3 UIDL command and the optional message number. When the response code from SendCmd is ST_OK, the response values are stored in Dest. 

Values from the POP3 UIDL command consist of the message number folowed by a space character and the unique-id for the message. The unique-id of a message is an arbitrary server-determined string, consisting of one to 70 characters in the range 0x21 to 0x7E, and uniquely identifies a message within a POP3 mailbox. 

Messages marked as deleted are not included in a UIDL listing.
