I've only just subscribed to the list, but in reading through the back-issues have come across a bug with dovecot-lda that was reported previously, and I can reproduce.
Using dovecot-lda CVS with Revision 1.21 of deliver.c (as newer versions won't compile against 1.0-alpha3), with dovecot 1.0-alpha3 and postfix 2.1.5
Rredirects mangle some headers - the 'To:' header ends up as:
To: undisclosed-recipients: ;
And there is no subject header.
Running sendmail from the cmdline with:
sendmail -i -f '<>' -- destination at address.com <msgtext>
as suggested to test by *Timo Sirainen *results in a correctly formatted message.
The mail_send_forward function in mail-send.c looks sane from what I can see, but then I'm not a C coder...
Any clues guys?
Cheers, Pete
