For me, this function returns FALSE if uid does not match a message in the current mailbox.
imap_msgno
(PHP 4, PHP 5)
imap_msgno — 指定した UID のメッセージ番号を返す

( resource
$imap_stream
, int $uid
)
指定した uid のメッセージ番号を返します。
この関数は、imap_uid() の逆の動作となります。
返り値
指定した uid のメッセージ番号を返します。

<p>Note that imap_msgno() doesn't ever give you an error message. So, assuming you're passing about message numbers as a UID, be warned that:</p>
<p>$msguid = false;<br>
$msgno = imap_msgno( $your_initialized_connection, $msguid );</p>
<p>Will leave ($msgno==1) - this is probably not what you want, and it's surprisingly easy to miss while you're doing the basic testing.</p>
