Just an idle Sunday question... how long do you have your mail server(s) configured to queue and retry messages before bouncing them back to the sender?
I know back in the day, 5 days was the norm, to handle servers that were only sometimes connected, outages, etc. I think that's still the default in most software. But that seems really long now. I took a quick look at some of my logs, and out of 4.6 million messages relayed to outside servers, 134 of them took longer than 12 hours. Of the messages that took longer than 1 minute, 77% were relayed within 1 hour (probably greylisting). Of the messages past 1 hour, 80% were relayed within 6 hours. I've got the queue life set to 1 day on some personal servers, but I'm wondering if I should go even shorter. For the most part, users don't really understand warnings and all - they'll be best server by getting a bounce as soon as practical. Anybody know what the big guys (Google and the like) do? I thought about setting up an address to always return 4xx and sending tests, but I'm lazy so I figured I'd ask here instead. :) -- Chris Adams <c...@cmadams.net> _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
