Hello list, I am having some difficulties understanding the null-client setup in the MULTI_INSTANCE_README, more specifically with the "mtaadmin" address group that is used as an example.
I understand why /etc/postfix/generic is used to rewrite local "root" user to "mtaadmin+root=mta1" in the example. What I am not sure about is the "mtaadmin address group" as it is called in the readme. Does the example assume "mtaad...@example.org" is a valid recipient at [mailhub.example.org] or is it assumed that "mtaadmin" is aliased to the "real" external recipient(s) in another place? >From /etc/postfix/virtual it looks like "root" is aliased to a local user "mtaadmin" which would mean it is another alias to the real recipient? In my test configuration I have replaced "root mtaadmin" with "root final.recipi...@external-domain.com" in /etc/postfix/virtual which will give me the mails with the correct headers as per the example mail to my preferred account, but I am not quite sure this is how it is supposed to be configured. I hope you can help me clear up my confusion. Thank You, Jay
