Hello to all,
I need to configure postfix to use multiple smtp relayhosts for a single
domain.
This is possible? How?
Your question is not entirely clear, so I'm going to answer as
if "single domain" refers to a single outbound destination,
with other outbound domains delivered directly.
Use transport_maps and MX records to direct mail to the group
of hosts you want, or use multiple /etc/hosts entries.
An example:
# main.cf - tell postfix to use a transport table
transport_maps = hash:/etc/postfix/transport
# transport - domains that get special treatment
example.com smtp:example.local
# /etc/hosts - host <> IP mapping
10.1.2.2 example.local
10.1.2.3 example.local
Or you can define example.local in your local DNS server.
