Hello, I have a problem with RoundCube. In general it uses LF as a newline symbol, but during splitting long headers it inserts CRLF. Also all newlines in message body are CRLF. This causes problems with mails' reading. Where should I look? Please help!

My system in Debian 4.0, PHP 5.2.0, Apache 2 and Postgres 8.3 (from backports).
