Multiple relayhost

[Jean-Sebastien Pilon]

Hello,

I am trying to setup postfix to relay to several relayhosts for failover
purposes. When I put 2 relay hosts in the relayhost parameter it returns
an error message.

fatal: relayhost parameter setting must not contain multiple values

How could I achieve this?

Thanks.

The relayhost parameter is subject to MX DNS-RR lookups unless enclosed
in [] or disable_dns_lookups is set to yes. Even with [], it is subject
to "A" DNS-RR lookups (with the default setting of smtp_host_lookup and
disable_dns_lookups). So you can use DNS to define weighted MX records,
or (implicitly) equal weight A records.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
