I see, well this really isn't your issue any more, its been delivered successfully, what the users ISP does with it is out of your hands. The user should be talking about it to their IT admin. > > Why does exim try the secondary MX, shouldn't it try the primary MX an hour > later or something ? > What would be the point of having backup MX servers then? Mostly I use backup MX servers for when the primary server gets too overloaded (e.g. spam/virus surge), the backup then accepts the mail, and then once the primary server is no longer overloaded, all the email sitting on the backup gets fired off to the primary server within a couple of minutes (due to some changing of the retry rules). This way the end users don't have to wait for the sending server to reattempt to send the email, which may be several hours (depending on the server software). What the user should be doing is removing the ISP's mail servers from their MX records, as having them there defeats the purpose of using grey listing in the first place.
