[Dovecot] Strange behaviour for sieve_before

[Simone Caruso]

Hi all,
i moved from dovecot 2.0.15 (lda) to 2.1.5 with lmtp transport, all works well
with the same configuration directives.

But sieve_before stopped working with mail_debug=no.
The weird thing is that, with mail_debug=yes the sieve_before script starts working.

Any idea? Thanks

(my conf attacched, for the new install i used prebuild packages)
