Pipe and replace message

[David Santinoli]

Hallo,

I could not find a way to pipe a message to an external filter and have
the output replace the original message.  As a workaround I open the
message in vim, pipe the whole buffer to the filter, and save it back as
a new message while the original one gets marked for deletion.
It works but it's a bit cumbersome.  Anything more straightforward —
possibly from the index screen?

I'm using mutt 2.1.4 as included in Ubuntu 22.04.


Thanks,
 David
