Hi guys, I would like to start a discussion about support for SRV records, mainly record for submission service of a domain. As is stated in [0], domain can publish dns record, which tells services where the submission service of this domain is. This could be used for auto configuration of postfixs relayhost option. I used this patch [1] to make postfix 3.5.4 support resolving of this: "relayhost = [_submission._tcp.$mydomain]:587" as a valid host for submission of mail in my domain. This will allow users to automate their configurations a little more. I would like to know your opinion and whether this could be officially supported. Thanks for any help.
