Hi! Is it possible to accomplish a gradual shift of traffic from one mail relay to another via postfix?
I'd like to move quite a huge mail stream from one mail relay (set via "relayhost=") to another but the latter should be "warmed up" to avoid delivery issues. Is there a way to redirect e.g. 10% of traffic to another relay via postfix configs? I'm also thinking about having ten hosts in the MX record (9 are for the current server and 1 is for the new one) but it looks rather ugly... Any advice, please? With my best regards, Danil Smirnov
