postfix redirect mail to transport going round relayhost

Question

I have worked correctly postfix with this setting:

main.cf

smtp_sender_dependent_authentication = yes
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_map
transport_maps = hash:/etc/postfix/transport
relayhost = [not.exist.dom]:555

relayhost_map

# postmap hash:/etc/postfix/relayhost_map
@my.sender.exemple1.com [my.reley.hos1]:7454
@my.sender.exemple2.com [my.reley.hos2]:7454
@my.sender.exemple3.com [my.reley.hos3]:7454
@my.sender.exemple4.com [my.reley.hos4]:7454

transport

#   postmap /etc/postfix/transport
[email protected]   emailport4:
[email protected]   emailsport2:
[email protected]   emailtransport1:
# with this sender_dependent_relayhost_maps not work
# *   newtransport:

Question: How to replace destination relayhost = [not.exist.dom]:555 to new destination newtransport?

Answer 1

1) update postfix from 2.66 to 3.1

2) add to main.cf

sender_dependent_default_transport_maps = hash:/etc/postfix/relaytransport_map
default_transport = newtransport:

3) /etc/postfix/relaytransport_map

# postmap /etc/postfix/relaytransport_map
@exemple133.com smtp:
@exemple12.ua   smtp:
@exemple1.com   smtp:
*   newtransport:
