[Dovecot] header brakage on sieve redirect ?

Hi all,

In the sieve file

require ["copy"];

redirect :copy "asdf@asd.pl";

emails with headers containing \n in non terminated " field

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

after redirecting them

Cc: xxx xxx@plus.pl, "asd,\

Grzegorz " xxxxx@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
