New to list, been using postfix for a little while. I would like to point a postfix install to two outbound relay's (all outbound mail to go thru them) so that, should one be unavailable, it will attempt to send via the other. Not "round robin" but "fail over".
This is probably simple, but have not found a clear description of how to. Is it as simple as adding a second IP, comma separated? Thanks.
