Hi all, 1. If a mail is temporarily deferred from a remote MTA, postfix should back-off instantly for some time but I observed this today.
Jul 24 06:40:16 server.name postfix-smtp4/smtp[6204]: DEC8B4F0185: host mta6.am0.yahoodns.net[98.138.112.35] refused to talk to me: 421 4.7.0 [GL01] Message from (1.2.3.4) temporarily deferred - 4.16.50. Please refer to http://postmaster.yahoo.com/errors/postmaster-21.html Jul 24 06:40:16 server.name postfix-smtp4/smtp[6204]: DEC8B4F0185: host mta6.am0.yahoodns.net[63.250.192.46] refused to talk to me: 421 4.7.0 [GL01] Message from (1.2.3.4) temporarily deferred - 4.16.50. Please refer to http://postmaster.yahoo.com/errors/postmaster-21.html Can anyone explain why would this happen? 2. I've multiple transports defined in master.cf which bind to different IPs. When a mail is deferred, will it always be tried via the same transport? If yes, is there a way I can change this behaviour? -- Regards, Abhijeet Rastogi (shadyabhi) http://blog.abhijeetr.com
