Is that the same as what you mean by "whether the message has
attachments"?  Please help me understand this ... the trace showed:

    FETCH 1 (BODTYSTRUCTURE FLAGS)

Presumably, imap_fetchstructure() generated this.  Then IMAPd replied:

    1 FETCH (BODYSTRUCTURE ("TEXT" "PLAIN" ("CHARSET"
        "US-ASCII" NIL NIL "8BIT" 1246 53 NIL NIL NIL) FLAGS (\Seen))

Is this being used to determine whether the message has attachments?

It looks like the only c-client interaction is the BODYSTRUCTURE
string in the FETCH request.  Can't imap_fetchstructure ask for that
too, if we modify it?

Excellent!
