It is okay to use names there. Here is a pointer to the postfix documentation for relayhost. http://www.postfix.org/postconf.5.html#relayhost On an intranet, specify the organizational domain name. If your internal DNS uses no MX records, specify the name of the intranet gateway host instead. In the case of SMTP, specify a domain name, hostname, hostname:port, [hostname]:port, [hostaddress] or [hostaddress]:port. The form [hostname] turns off MX lookups. Examples: relayhost = $mydomain relayhost = [gateway.example.com] relayhost = uucphost relayhost = [an.ip.add.ress] Two of the examples specifically list hostnames in brackets to turn off MX record lookups. The real question is whether domain search is supported or not. Previously simple host names without a domain part were allowed there. The documentation in that section doesn't say as to whether this is or is not allowed. It might say elsewhere as a more general statement however. Frankly I wasn't sure where to look and didn't find it after a search. I am okay if short host names are no longer supported there. But this is the type of subtle change that can slip in unexpectedly. If it is intentional then having been found it would be good to add a NEWS entry and I would be happy to write a NEWS entry addition suggestion. But I am still thinking this is an unintentional and undesired change and so holding out. :-) > And you must be sure that "mail" is correctly resolved.
