How to handle multiple domains hostname
Posted: 21 Nov 2020 07:04
Hello everyone, I'm a recent migrated user from ESVA2 and I'm loving the level of documentation available for efa (why didn't I move before!?)
My setup is simple:
Internet Mail --> efa --> Exchange
However, the Exchange server hosts email for several domains and I have configured multiple hostnames in /etc/hosts
For example
192.168.1.1 hostname.domain1.com
192.168.1.2 hostname.domain2.com
Is there a way to configure the SMTP banner to respond with the correct value depending on the IP address?
Ultimately, I'm looking to eliminate reverse DNS mismatch errors (Reverse DNS does not contain the hostname, Reverse DNS is not a valid Hostname, Reverse DNS does not match SMTP Banner)
What is the correct way to configure this setup?
Thanks in advanced!
