The best we can do is cross-reference the new parameter under smtp_bind_address (and IPv6 equivalent), and then sufficiently motivated users can find out how to make the setting a mandate rather than a suggestion. To me this looks like a reasonable feature request, despite the fact that nobody else had asked for it in the first 24 years of Postfix. So by no means urgent, but sensible. -- Viktor.
