Alright, I understand.
However, I just realized that I actually might not need to change the domain.
The -o overrides I need may only be the smtpd_tls_* settings. I was just
concerned about name mismatches with the certificate, but whatever postfix
thinks is the domain shouldn't affect the client's matching the domain name in
the certificate itself to the domain it used to connect. Therefore, perhaps
this proposal would NOT be outside the scope of what you find acceptable?
1.2.3.4:smtp inet n - n - - smtpd
-o smtpd_tls_cert_file=/etc/postfix/domainA.crt
-o smtpd_tls_key_file=/etc/postfix/domainA.key
4.3.2.1:smtp inet n - n - - smtpd
-o smtpd_tls_cert_file=/etc/postfix/domainB.crt
-o smtpd_tls_key_file=/etc/postfix/domainB.key
