Let's say my domain is example.com. We have a bunch of servers that

outside with something like :
mynetworks: 192.168.250.0/24
So far, so good.
Now I have a sister organisation with domain example2.com that
operates a web app than needs to send mail through our Postfix server
and I want to relay mails sent from this web app provided the
messages sender meets a specific email address (say
web...@example2.com).
How can I do that in main.cf ? Simply adding the web app server IP to
mynetworks would not do the trick since I'd rather not relay any
email traffic from this server, only this webapp messages
(notwithstanding fake headers).
I read through smtpd_reject_unlisted_recipient and
smtpd_relay_restrictions documentation but could not figure out how
to do it.
configure SMTP authentication instead of playing with this.
