I suspect the problem is in there somewhere: either the domains that are bouncing don't have MX records or they are doing a reverse lookup on wc.edu (e.g. for spam protection) and getting the wrong server's MX record.

The DNS information might be out of sync or lagging. Just need to make sure they are serving up compatible/similar information. If xxx domain is only hosted by a certain DNS server and the exchange server is getting it from that one, but the MacOSX one isn't, then there is a potential spot for the problem. 2) Does the Exchange server have any internal hard-coded host->IP entries or routing rules for the domains with the problem? Ie, domain masquerading for xxx domain on the exchange server, but not on the MacOSX server? 3) Is there any host information which is residing in Active Directory or LDAP/etc that isn't being accessed or referenced by the new host? I second the idea that DNS is the cause of the problem. Since there are potentially other host resources that exchange could be referencing, it is worthwhile to determine if there are additional rules that may have been missed.

Now that makes sense. I don't know if my boss did a reverse DNS for kyrie. I do know that we had that problem with the old mail server until we put one in place. Let me go see. Thanks!!

(server87.appriver.com has 2 ip addresses assigned). So those systems have forward entries. Do you have login access to the mail servers? If so, what do you get when you perform a nslookup, host, or dig on the ccccd.edu and server87.appriver.com hostnames from the mailserver? I did a test query against server86 and server87 with that email address and it indicated that it will forward to that address. (telnet'ing to smtp port) Did it just need a little more time to sync up? Ie, is it working right now?

Btw, I'm not including what you emailed to avoid the 5KB limit. I also went back and re-read a post you emailed, that I missed. >From the info you sent: The DNS servers internal to your network don't have A records for server86 and server87. The next step would be to add A records to the DNS server(s) for server86 and server87 to the DNS server 67.67.182.10 or it's master, if it is a slave. I know in sendmail, you can designate a particular email relay as a "smart host" to handle problem emails. I'm wondering whether the Exchange server might not have some setting like this. But right now, I'd make sure that DNS has the correspsonding A records for server86 and server87 in the internal network. I'd also check to see whether ldap has the corresponding records, if you are using ldap for hostname resolution. The only other things I can think of off the top of my head is to check the MacOSX email server to verify which DNS server it is using for name resolution and that it contains the A records in question. Btw, I've been assuming that emails that are being sent are being sent on the internal network to other internal users and to internet users. Please let me know if this isn't the case.
