sieve redirect to foreign email gets "Relay access denied"

Question

I have a postfix mail server with sql authentication and I want to implement sieve on it.

Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. So practically a email coming from [email protected] for the local user [email protected] should be redirected to [email protected] when the subject contains "redirect"

if header :contains ["subject"] ["redirect"]  {redirect "[email protected]"; stop;}

when I test it I get the following log entry

postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.server.net>

How can I tell postfix to let dovecot/sieve relay the email?

can somebody give a hint?

I don't know for certain, if Pigeonhole implements client SMTP AUTH, but I found no setting for it. On the other hand, you can use a sendmail script instead of SMTP to circumvent that limitation.

See:

# Binary to use for sending mails.
#sendmail_path = /usr/sbin/sendmail

# If non-empty, send mails via this SMTP host[:port] instead of sendmail.
submission_host = localhost 

ALSO There is something called SRS Sender_Rewriting_Scheme, that would create the possibility by adding and removing some headers to transform a normal email in a enveloped email. There also is a RFC 5293 that specifies the sieve commands "addheader" and "deleteheader" what permit alteration email but it seems like Pigeonhole Sieve is not supporting it yet.
