Migrating from POP to SMTP and Exchange 2010 - Configuring Firewall and Send/Recieve Connectors
Posted on 2010-11-23
My company currently uses POP email that is hosted by one of the larger carriers which of course is where my MX records are pointing.My users just check that mail with Outlook.It has been sufficient in the past but we are looking for some more functionality so I am in the process of migrating to Exchange 2010 and hosting our own email. My server is built and operational locally. Windows Server 2008 R2 running on a HP DL385 with almost a terabyte of storage.I've also allowed SMTP traffic to pass through my Firebox firewall. This same carrier offers a Secure Email Gateway that I plan to use to filter spam,etc. I realize of course that I will need to update our MX record to point to that gateway once I'm ready to switchover however they are recommending that I get my Exchange server fully operational prior to going through their gateway,which to me sounds like 2 MX record updates? Their reasoning is to insure I don't have any problemswith my Exchange box. I'm not using the Edge transport portion of Exchange.....anyway one of my questions concerns send and receive connectors. I would need both send and receive correct? Would this be my firewall or when I switch the Secure Email Gateway? I'm not sure if I understand this concept. Sounds like a relay of sorts? I read somewhere online that I could configure my Outlook clients for both POP and SMTP where I'm sending using SMTP and Exchange and all my replies are coming back to our POP service provider and I can collect it as usual with Outlook and then remove the POP accounts one by one. If anybody has recomendations or suggestions on how I can simplify this task I would greatly appreciate it. I tried configuring an Exchange only Outlook client and attempted to send to an outside recipent but the message just sits in the Que saying it has no connector or something? Last Error: A matching connector cannot be found to route the external.
