Hi everybody,
I posted on r/postfix but it seems not to be so active any longer :-(
I know this might sound as a quite complicated question but here you go:
I need to setup a mail gateway to allow a certain amount of hosts in a
LAN to send out mails and still pass SPF/DKIM/DMARC checks. Also, not
all hosts in the LAN will be authorized to send mails and I want to keep
some sort of traceability for the end user.
My idea is to control who is authorized via `mynetworks` and up to here
is all fine. The second thing I want to do is rewrite the from address
based on the source ip, e.g.
10.1.1.1 -> FROM: j...@test.co.uk
10.1.1.2 -> FROM: m...@test.co.uk
I saw many things going around filters and the check_client_access but I
didn't get if it's possible or not.
Appreciate any help! Thank you :-)
All the best,
Marco
You can do that with milter-regex or some other milter.
