virtual folders, virtual groups?

[Uwe Brauer]

Hello

As a long time user of VM I enjoyed very much  what is called, virtual
folders.  This feature allowed  by in  my INBOX, to  select msg, whose
subject, recipients or  whatsoever satisfied a certain condition.  For
example all msg  with the subject: POSSIBLE SPAM  would  appear in one
virtual folder.

I know I can *sort* msg in  my group buffer,  but it would be handy to
create a virtual  group, in the same spirit  as above. I looked in the
documentation of virtual groups  but it does not seem  to me  the same
thing I am talking about.

Thanks
