I have an exchange server that we moved from another building to a new one. We had to change ISP providers and get a new external ip address. What needs to be done to set up with the new ISP provider and the new external ip address? Do I change the MX record and A record to point to new external ip address? Is this right and what else might I do. Do I have to change any setting on the exchange server itself? Thanks

- 1. Internal and Extarnal DNS name for Exhange5.5
I has Exchange5.5 server behind ISA firewall. In Internet my mail server has name mail.mydomain.com, but in local network it has name mail2.myHOMEdomain.com (myHOMEdomain is virtual, is not registered in Internet) When I send mail to Internet the server in header of mail write mail2.myHOMEdomain.com and some of mail servers does not receive our mail because error: 450 <mail2.myhomedomain.com>: Helo command rejected: Host not found What can I do ? How change server name that it write in all message to Internet ? - 2. How do I configure the front end to be an smtp gateway?
I have an exchange 2003 front end server in the DMZ and a 2003 Back end server. The front end is only being used for OWA. The Back end has an smtp connector to the Internet and processes all inbound and outbound mail. I want to move this function to the Front end. I want to configure the front end so that all incoming mail goes to it (i know i have to change my mx record) and the front end sends it to the mailbox on the back end. This setup would also require the back end to send in outbound mail to the front end for delivery. Is there any good doc on how to set this up? - 3. SMTP Connector in SBS2k3
I am having trouble sending mail to aol.com and earthlink.net addresses from all PC's in the network all running XP Pro sp1 & outlook 2k3. I am running SBS 2003 premium will all critical updates. When we send a message we can see it in the SMTP Queues. the message sits in the SmallBusiness SMTP connector - aol.com (aol connector) Protocol SMTP Soruce Default SMTP virual server State Retry We have no trouble sending or recieving any other domains, earthlink says they are not blocking and the users are not blocking the messages. Is it us?

Your Exchange server's most likely using internal/private IP addresses - if that's the case, as long as your internal IP addressing is the same (in your new building), you don't need to change anything on your server. - DNS: Yes, A record should map to new external IP address, no change required in MX - it points to the A record. - Firewall: If you're using a firewall/NAT, you'll need to make changes to the IP addresses and NAT rule(s) on the fw. -- Bharat Suneja MCSE, MCT www.zenprise.com blog: www.suneja.com/blog -----------------------------------------

1.Changing Exchange 2000 server IP address and entire netowrk IP addresses
We are planning to change our Internal pool of IP addresses; what will be the best way to to create additional pool of IP addresses in Windows 2000 Server what will be the impact Exchange after the IP address has changed? What needs to be done after the IP address has changed, do I need to apply any service packs or updates? How many IP pools can I create in Windows 2000 server environment?
Prior to a network change we used NAT (public/private IP addresses) in our firewall to access Exchange. The public IP had a host DNS records as well as reverse DNS pointer record. We switched to port forwarding in our router. All NAT is gone. The problem: outgoing mail now shows the router public ip as the ip for the sending server. Consequently reverse DNS lookups fail at receiving email servers. Is Exchange aware of the public ip in this scenario? Should I just change the host and ptr records to point to the public ip of the router? Are there other options? Thanks, Tom
3.Change of External IP address
Hi, We are moving premises at the weekend and I need to sort out out email. We currenlty run Exchange 2007 and have an MX record pointed to our external IP address. When we move, we will be allocated a new IP address (ISP can not move IP address!). We will also be waiting a few days for our new ADSL service to be up and running. What options do we have so we can still use our exchange server to continue receiving email? Any help would be appreciated. Many thanks, Jamie
4.SBS-Exchange only sends email to my ISP provider email addresses
I have SBS installed and everything seems to be working except I can't send external email, excpet to my ISP provided email. I get email from what appears to be anyone. I get my ISP through SBC Yahoo and coincidentally emails to them go through. I have not found any other emails that work. I suspect DNS, so I added my DNS IP addresses provided from my DSL connection to the SMTP External DNS table and that doesn't seem to have made a difference. Any Ideas?
