Maybe its worth noticing that adding line

--8<---------------cut here---------------start------------->8--- Return-path: a@b.c --8<---------------cut here---------------end--------------->8--- to example message makes dovecot-lda working.

Which revision of the extprograms plugin are you using? As of changeset 47 the Return-Path manipulation has been removed, so if there was a bug in that code rebuilding with the latest version may make it go away.

Otherwise, can you get a backtrace? It would be more use if you can rebuild with debug symbols, but even without it should give some useful information.

I don't know if I did it properly (how to compile it with debug symbols?)

After sending previous post I realized that debug symbols should be in dovecot-dbg package. Below backtrace:

raw-storage's envelope_sender is NULL. Fixed Dovecot to make sure NULL isn't returned: http://hg.dovecot.org/dovecot-2.1/rev/579984fdb6e5

But I think Pigeonhole also shouldn't set it to NULL. sieve-message.c:sieve_message_get_sender() apparently returns NULL if it can't find anything. Elsewhere this is used when nothing else is there:

#define DEFAULT_ENVELOPE_SENDER "MAILER-DAEMON"

LDA from dovecot 2:2.1.12-0~auto+10 does not segfaults. Thanks.
