Here is a simple working snippet to properly check the return value of imap_msgno():

$id = imap_msgno($imapConnection, $mailUid); //convert to normal messagenumber in current context
$verifyUid = imap_uid($imapConnection, $id);
if ($verifyUid != $mailUid)
  throw new Exception("Attention: imap_msgno returned nonsense!  The mail was probably not found in the mailbox!");

For me, this function returns FALSE if uid does not match a message in the current mailbox.

<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>
