I just checked mozilla, for messages on a imap server. So mozilla
does not seem to add anything to the header, no new X-whatsoever
field, but instead seems to storage the label in another place. 

Moreover I  used mozilla to set a label which also was understood by
mozilla-thunderbird, although both seem different directories for
their setting and local information. So I am now puzzled where is this
information stored.

If this is a general enough place somewhere on the imap server, may be
gnus could read and display it as well.
