imap_setflags_full Seen

I am trying to use this: imap_setflag_full($imap, $uid, "\\\\Seen", FT_UID) or die("Unable to mark message as \\Seen"); to mark a message as "read" It does not seem to have any effect on the return values in imap_fetch_overview. Nor does it appear as "read" when I view it with my email client. The "unseen" count on the mailbox also does not decrease, which I would expect if it was "working" Is there some kind of trick I'm missing? Is there some OTHER flag/function I'm supposed to be using to mark a message as "Read"? I sure can't find it in tfm so far... The $imap stream is valid, and I can fetch the headers and body just fine. The $uid is from imap_uid and, again, is used to fetch the header and body just fine. I've tried imap_close($imap, CL_EXPUNGE) in the hopes that it would "write" the changes, but no such luck. PHP 4.4.7 Hardened Gentoo 2.6.18 hardened R6 SMP phpinfo says IMAP c-client Version 2004 w/ SSL support enabled Gentoo says courier-imap 4.0.6-r2 is installed, so probably using that. The versions are out of my control, due to a security and stability focus of this install. -- Some people have a "gift" link here. Know what I want?
