Here is the domain listing from the ISP (edited for security reasons)

Server: server.isp.com
mydomain.com SOA server2.isp.com dns-ip.isp.com.
mydomain.com NS server2.isp.com
mydomain.com NS server3.isp.com
mydomain.com MX 10 main.mydomain.com
mydomain.com MX 20 server.isp.com
main A xxx.xxx.xxx.xxx (static ip)
mail CNAME main.mydomin.com

ok here is theproblem: When we were on dialup the exchange would dial and use a dequeue command to force any stored email at isp to come down to our server. Now that we have swiched to a persistant DSL connection the mail should be coming in to us live, but every morning it seems we get a mass of e-mails from the night before yet the DSL has been connected the whole time. To make it even stranger sometimes in that group of e-mails one will show up that is like 3 - 5 days old.

Anybody have any ideas???

P.S. I am not the ISP so if you are recommending changes to there side give me an explanation so I can explain it to them.

Thanks

Is Exchange being shut down at night for some reason - for example, for an off-line backup? This would certainly cause the behavior that you're describing, so I'd check this first. I noticed that your ISP is listing two MX records - main.mydomain.com and server.isp.com. This seems to indicate that your ISP is providing a backup mail server for you so that if your server is offline, the mail will be stored on their backup server until your server comes back online. If your Exchange services are being shut down for some period of time at night, then the ISP's backup server would be storing your email. When your Exchange services come back online, there may be somewhat of a delay before the backup server starts dequeueing the saved mail (this usually happens automatically although many ISPs will allow you to issue a manual ETRN command to their server if you so wish). This also might account for some messages being several days old - when the ISP's backup mail server can't deliver a particular email message, it may store that message for up to 7 days and keep trying to deliver it. Hope this helps!
