[Dovecot] Sieve pipe extension - can it retur something?

[Kamil Jońca]

I have a question about sieve pipe: can it return something to further
processing?
For example in procmail I can do:
--8<---------------cut here---------------start------------->8---
:0
VIRUS=`$CLAMSCAN --mbox --disable-summary --stdout -`
--8<---------------cut here---------------end--------------->8---
and then test VIRUS variable.

Maybe I missing something, when read
