Are you perhaps referring to auto configuration of a client’s MUA (like how on Apple iOS devices you enter the e-mail address and password and then Apple Mail discovers submission, IMAP, etc. settings and so forth) ? The RFC that covers that is RFC 6186 - “Use of SRV Records for Locating E-mail Submission/Access Services”. This is done in DNS and is not Postfix-specific. If I recall correctly, one restriction is that the SMTP AUTH account name that is used must be the same as the e-mail address - so if you have AUTH account names that differ from the e-mail address, this is an issue.
