imap_body with FT_UID option

[s_boucher@hotmail.com]

Hi,

I'm trying to fetch the body of a specific usenet message using the
imap_body function with the FT_UID option (The msg_number is a UID).
My understanding is that the UID is the string that looks like this:
<1126793330.520 771.201070@g49g 2000cwa.googleg roups.com>

So after I have a successful connection ($nntp), I try:

$msg_body = imap_body($nntp ,
'<1126793330.52 0771.201070@g49 g2000cwa.google groups.com>', FT_UID);

And I get:
Warning: imap_body(): Bad message number in ...


Any idea what I am doing wrong?

Thanks!
