Hi all, I'm setting up an Haproxy load balancer for multiple Postfix instances. The balancer forwards smtp traffic to a dedicated postscreen service on every instance. Every instance has its own $myhostname and exposes it on the smtp banner so it happens that the FQDN and PTR of the balancer do not match the hostname presented in the SMTP banner. Online tools like MXtoolbox complain about the mismatch while checking the mailserver. I thought to configure every Postfix instance whit the same hostname of the balancer. This gets the rid of the mismatch complaints but keeping a different hostname per instance would help in case of troubleshooting, so I ask if there is a better way of doing this.
Thanks Giuseppe -- Giuseppe Civitella gcivite...@entermail.it
