<?php

$connection
= imap_open(...);
$messageUid = 123;

imap_clearflag_full($connection, $messageUid, '\\Seen', ST_UID);

I got a note that:

if u want to set a mail to "//Unseen", which not exists,
do it like this:

imap_clearflag_full($your_imap_connection,
$number_of_message,"//Seen");

but, remember to do
imap_close($imap, CL_EXPUNGE);
@ the END! so that it will be confirmed!

Cheers,
Nohado

Remember to specify your flags like '\\Seen' rather than "\\Seen".

Of course, flags are an IMAP feature, not a POP feature.

Resetting \\Seen works from PHP 4.3 works fine on the modern mail servers I've tested.

imap_clearflag_full() and imap_setflag_full() seem to only change messageflags permanently with IMAP connections, not with POP3 connections.

This function seems not to save the \\Seen flag permanently.

Testet on Win NT IIS 4.0 PHP 4.3 and imap-mail-server
