May I should explain a bit more what i want to do..
I'm migrating my mail system from an old, buggy, Groupwise system to
Postfix. The migration will take several month as I can't migrate all
users at the same time.
I want the following behaviour: all migrated users use the Postfix to
send mails. On Postfix, if the user does not exist (ie, the mailbox is
still on the Groupwise system), so i want to configure Postif to send
the mail to Groupwise if he does not know the user.
- define the domain as a relay domain (put it in relay_domains, not
elsewehere)
- if you can, dump the list of valid recipients and use it to populate
relay_recipient_maps
- if you can't, use reject_unverified_recipient at the end of your smtpd
restrictions. This assumes that tour groupwie validates recipients.
- in any case, start gathering the list of valid recipients.
