Changes in sieve Dovecot 2.2

Hi People,

I'm use dovecot in my mailbox system, until last month i used the dovecot version 2.0 and now i use version 2.2, version 2.2 works well for me, but i have one small problem, in sieve.

In version 2.0 i had rules in sieve similiar to rule bellow:

if allof (true){ keep; fileinto "INBOX"; redirect "xxxxxx"xxxxxx.com.br"; stop; }

In the new version 2.2 this rules above, i have one problem duplicate messages in account from my clients, in paste INBOX, therefore, i changed rule to bellow ( with remove fileinto inbox)

if allof (true){ keep; redirect "xxxxxx"xxxxxx.com.br"; stop; }

Dovecot really changed your behavor, i did right to fix this ?

Thanks a Lot, Marcelo
