Hi,

Can't find answer, about postfix dns preferences and dns lookup performance.
Let's say I have relayhost with FQDN: srv2378948273.mydomain.com

I'd like to create a DNS Alias record or A record to use more friendly name:

relayhost1.mydomain.com

Does postfix prefers A record more than DNA Alias ?
And is there any performance or other issue with Alias records ?

Best Regards,
John
