[IMail Forum] DNS troubleshooting assistance request (causing mail problems)

[Katie LaSalle-Lowery]

Yesterday we became the DNS authority for a domain, ifs-mt.com.   They have an Exchange server.  Their Exchange server's IP address was and remains 69.51.79.204.   I created an A record for mail.ifs-mt.com for 69.51.79.204 with an MX record for mail.ifs-mt.com.   At my location we have an Exchange server (mail.emerycomputer.com) and we have an Imail server at a remote location.  When I send from our Exchange server the mail is delivered.  When I send through our Imail server it is not.  When I test from a Yahoo! account it does not get there.  They are not getting emails.  When I do an nslookup from our Imail server it resolves correctly but when I look in my Imail log it doesn't look like Imail is using the right address.  Since the address never changed that perplexes me.   When I nslookup or ping I resolve to 69.51.79.204.  When I test from dnsstuff.com it looks good.   If some of you would test from your end and report results I'd appreciate it.    Thanks! ~Katie
