Hi, Is there a way to change my hostname based on the relay i'm using?
For example, i have postfix servers in an ha config that relays to three differents mail service providers, this providers restricts me in what helo i have to use; so if i'm using ISP1 as relay, i must identify as helo1.mydomain if i'm using ISP2 then helo2.mydomain... this it's really annoying but rules are rules. Then, i need a way to change the helo based on the sender_dependent_relayhost clause or something like that. I really don't want to break my ha loadbalancers. :) Is there a way? Greetings.
