You do not need different banners on different IP addresses
when you implement the following:
MAIL EXCHANGER POLICY TESTS
When a remote SMTP client is not on the permanent access list,
postscreen(8) can implement a number of whitelist tests before it
grants the client a temporary whitelist status to talk to a Postfix
SMTP server process.
By listening on both primary and backup MX addresses, postscreen(8) can
deny the temporary whitelist status to clients that connect only to
backup MX hosts.
postscreen_whitelist_interfaces (static:all)
A list of local postscreen(8) server IP addresses where a non-
whitelisted SMTP client can obtain postscreen(8)'s temporary
whitelist status to talk to a Postfix SMTP server process.
If the above required different banners on different IP addresses,
then surely I would have mentioned this.
If the above required TWO postscreen daemons running on the same
host, then surely I would have mentioned this.
I could write thousands of lines of documentation about all the
things that you don't need to do.
Or you could just take the hint: if the docs don't say something
is required, then it really is not required.
