[Dovecot] header brakage on sieve redirect ?

[Lazy]

Hi all,

In the sieve file

require ["copy"];

redirect :copy "asdf at asd.pl";

emails with headers containing \n in non terminated " field

like
Cc: xxx <xxx at plus.pl>, "asd,
 Grzegorz " <xxxxx at nsn.com>
Subject: RE: RF


after redirecting them

Cc: xxx <xxx at plus.pl>, "asd,\

\
 Grzegorz " <xxxxx at nsn.com>
Subject:  RE: RF

mail delivered locally by dovecot-lda is unaltered


lack of space before second \ brakes the headers.

I'm investigating if this isn't cosed by qmail-inject, but my first
suspect is sieve.

dovecot 2.0.13, sieve 0.3.3, dovecot-delivery is used as an exclusive
lda for qmail

Regards,

Michal Grzedzicki
