lda fails in parse_angle_addr if sieve is enabled

[Stephan Bosch]

Hi,

This code path is only executed when there is a return-path header. 
Given the fact that this fails consistently, can you provide an example 
of a message successfully delivered using an older version of Dovecot; 
i.e., as it is stored in the mailbox? There should be a return-path 
header there.

Alternatively, you could temporarily wrap dovecot-lda in a shell script 
that copies the message to some file you can read after.

I just need one example to confirm my suspicions.

Regards,


Stephan.
