Hi kashani,
I actually read about that option when I was trying to make this
happen (forgot about it when composing my original message). Googling
that option I found that most people were interested in combining
multi-recipient messages to one on disk (to save space). Indeed the
option is already set to "yes" on my setup, but I still don't get that
header. I supposed that it has nothing to do with the address I'm
interested in (from the envelope) and instead is looking at the To:
name from headers (which is unchanged). Or because my message does not
have multiple recipients. But maybe I'm completely misunderstanding
what it's all about.
Here's what an incoming mail to catchall looks like in my syslog:
Jul 4 22:11:10 virtual postfix/smtpd[3032]: connect from

So it does run cleanup (and before passing the msg to dovecot) and
there is reference to orig_to so at least I know postfix realizes
there's a difference. Maybe this should be done by dovecot instead?

As I basically followed the wiki, I have no idea if this config is
ordinary or not. :) Thanks again for your help.
Thanks,
