dovecot - Oct 2009 - failing to deliver to one of multiple destinations

Is it defined whether, in case a message should be delivered to  
multiple destinations via a sieve script, and one of those  
destinations fail, then the whole delivery is to be considered as  
successful or not?

My case:
A sieve script forwarding to and external destinations plus local keep.
The keep fails (configuration error, wrong homedir, .dovecot.lda- 
dupes not writable).
According to postfix logs, dovecot deliver returned success.
The mail was NOT delivered to the local destination and NOT bounced.

Is this expected behaviour?

No, when delivery fails entirely, the deliver binary should give an 
appropriate exit code, indicating that the MTA needs to try again later 
or bounce the message. What do the Dovecot and MTA logs say? 
Furthermore, the output of dovecot -n would help us find and solve the 
issue. And finally, your Sieve script may also be relevant.

OK, I would have expected that.

I will send you that information in private mail.

See above.

Thanks for your help.

OH NO! It seems to be entirely our fault.

After spending about an hour excerpting, editing and commenting the mail log
(Postfix->Dspam->Postfix->deliver/Sieve plus forward), and finally
pasting the Sieve script, I noticed there seems to be an error in my colleagues
forward-to-Sieve tranlation ommitting the keep after a redirect if the forward
file contains both an external address and the local one.

Sorry for the noise.
