There can be only one table entry with the name @foo.bar. The
postmap command ignores the rest with a warning.

Postfix 3.5 supports multiple relayhosts:
transport_maps example:
example.com relay:[mail1.example]:123, [mail2.example]:123, ...
sender_dependent_relayhost_maps example:
@foo.bar [mail1.example]:123, [mail2.example]:123, ..
This is a fixed order (as if you had multiple records in /etc/hosts).
If these folks want to receive mail in six places, why can't they
set up DNS records like everyone else does?
