Hello David, DF> well that's what the discussion has been about, search back a few weeks DF> for the replies to my thread on the subject of secondary mx's.
DF> If you have a secondary on the same site as your primary then it covers DF> you if the primary goes down but not if your site is cut off from the DF> net. You could then have a tertiary mx that is off site of course. DF> Or you could not have any. It is my understanding that a secondary MX will still reject the mail 5 days after just like any other mailserver on the net would if you don't have a server up and running that can collect the mail or redirect it to another server in that time, the only benefit for secondary MX's is if there is a dialup and the ISP has dynamic IP's etc and while everything updated etc... or having it on the same site, because then you shouldn't get hit with a surge of mail coming in once all the servers realise your server is back up, and like wise they won't try to hit a dead IP, they'll shift it along to the next preferanced server... there is a downside... the secondary can be used to spam you, as it can't check if they are a valid account until it's shunted to the primary or a server that deals with it... feel free to correct me if i'm wrong... /2cents -- Best regards, evilbunny mailto:[EMAIL PROTECTED] -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
