A reverse lookup zone was created on the external DNS server and a PTR record for the Exchange server without any luck in sending out e-mail. Funny thing is I can e-mail back and forth to Microsoft tech all day, but not anywhere else. Makes me say hmmmmm.
I did that yesterday after I saw what they did. They are slow in what they do. When I first switched over the tech that took the request laid it on her desk and went on vacation. Thanks and have a great weekend.
We have had problems from day one with the ISP. I'm bringing everything inside next month. The 172.30 is part of our internal domain and I'm wondering the same thing as why they are pointing here.
Yes our ISP currently collects and delivers our e-mail. Don't worry about asking too much. I appreciate your help here.
Here is a current copy of what Sprint has in our zonefile:
greatamericanproducts.net. IN MX 10 msmail
greatamericanproducts.net. IN A 172.30.99.200
msmail...
Yes, the firewall reroutes the outside Ip to the inside IP which allows incomming e-mail. The problem is with sending out. We have reverse DNS enabled, but still have this problem.
oneproblem.net is only registered outside. Our firewall redirects the inside to the outside IP. We can receive e-mails just fine, but get on and off send capability outside. I'm seeing this error on my firewall in the SMTP traffic log.
I have a problem and have a brain dump as to the fix. I get an error that says : oneproblem.net 199.99.99.34: can't verify reverse address - lookup does not include original address 198.88.88.32
The 199 is an outside address and 198 is the inside address. Would I use a loop in this situation...
I have an internal DNS server as primary and and external as secondary. The problem I'm having is I have an Exchange Server with an internal and external address. The external DNS will not do a reverse lookup of the internal DNS. How can I fix that internally?
I have a client who is receiving 2-4 copies of the same e-mail from the server. the client can open an e-mail and read it and the next time they look at their inbox, all the e-mails they have read are shown as unread. What could be wrong here? Virus?
