"Pipe to Program:

Evolution can use an external command to process a message, then process
it based on the return value. Commands used in this way must return an
integer. This is most commonly used to add an external junk mail
filter." - https://help.gnome.org/users/evolution/stable/mail-filters-co
nditions.html.en

IIUC it hands over the complete message.

There's no need to use

Pipe to Program ... returns ...

but it might be useful, too, while just e.g. deleting the mail could be
done without a return value, by the same filter.
