In that case, use sender_dependent_default_transport_maps to choose
an SMTP client with a the appropriate smtp_bind_address setting,
and use a FILTER action to override this for low-reputation mail.
/etc/postfix/main.cf:
sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport
milter_header_checks = pcre:/etc/postfix/milter_header_checks
smtp1_bind_address = 1.2.3.1
smtp2_bind_address = 1.2.3.2
....
smtp5_bind_address = 1.2.3.5
/etc/postfix/sender_transport:
A1.com smtp1:
A2.com smtp2:
... ....
/etc/postfix/milter_header_checks:
/^X-Foobar-Precedence: junk/ FILTER smtp5:
/etcv/postfix/master.cf:
smtp1 ... .... ... smtp -o smtp_bind_address=$smtp1_bind_address
smtp2 ... .... ... smtp -o smtp_bind_address=$smtp2_bind_address
...
smtp5 ... .... ... smtp -o smtp_bind_address=$smtp5_bind_address
