Well, yes, it is a bit restricted, but you could also use S-nail
v14.9.11 or later:

  $ printf 'dig c 25 -;dig 25 h s received;digmsg r 25' |\
    s-nail -#Rf +download

Where dig is actually digmsg, c is create, h is header, s is show,
and r is remove.  String matching etc. via the csop and vexpr
commands.
I have heared someone revived qmail and wants to include some
patches for builtin TLS etc.  That sounded very much interesting,
especially if its mailing-list manager would be maintained again!
