limit to single-mail 'threads'

[holger.dinkel@xxxxxxxxx]

Hi list,

I was wondering whether it was possible to 'limit' the index to those mails
which are NOT part of a thread.

On some mailinglists there occur spam-mails sporadically.
I thought of (tagging and) deleting them by limiting mutt to show only mails
which have no response to them.  (Nobody replies to spam-mails! ;-> )

Is this possible?
The ~Q limit pattern only considers mails that I responded to, right?
And the ~v limit doesn't apply either...

Any hints?

Best wishes
