You didn't mention what Dovecot version. That should be the From: field.
Depending on what Sieve you use the Subject: should be different.

But anyway.. looking at the current Pigeonhole code, it doesn't look
like it uses LDA's rejection_subject or rejection_reason settings at
all. Stephan, can you add support for those? Or is there a reason why
you can't use mail_send_rejection()? Maybe those APIs could be changed
to avoid all of this code duplication..
