Hi! can anyone please help me to understand how the nexthop works inthe transport table when using hostnames with multiple IPs?
For instance: example.com smtp:[gateway.example.com] gateway.example.com resolves to 3 IP addresses... - Will Postfix try to resolve gateway.example.com for each and every email? - What happens if one of the IPs are not responding? - If an email goes to the Deferred queue, when later on Postfix tries to send it again, does it try with the same IP of the previous try? Thanks, -Pete.
