Hi, I am just setting up Exchange2007 on SBS2003. I currently use a pop email account and pick up my emails that way, but now I want to run an Exchange server. I have tied into TalkTalk for a further year and can't get a static IP address. My question is how to collect mail to my domain (I have a registered DNS domain). I think I can use Dynamic DNS to overcome the dynamic IP address issue, although I'm not sure how this works exactly. I'm also wondering if I can set the Exchange Server to query my pop server for emails periodically, which would be the easiest solution until I can get out of this talktalk contract. By the way, steer clear of Pipex (now TalkTalk) as their business practices are dubious to say the least and caused me no end of headaches.

Hi, I am just setting up Exchange2007 on SBS2003. I currently use a pop email account and pick up my emails that way, but now I want to run an Exchange server. You mean either Exchange 2007 on SBS 2008, or Exchange 2003 on SBS 2003. Both of these products come with a POP3 Connector. So this is a good start. And you should use the same SMTP server as you use now (at your ISP) as a smart host. Let's concentrate on SBS 2008 with Exchange 2007. That's what I'm using at home (mostly with Snow Leopard and Entourage, but that is another history). Be very careful when you configure SBS in general. If there is a wizard for a task, use the wizard. Make sure that you set up all your initial Exchange settings through the wizard. Here you will add your registered domain name. Let's call it hosle.net. You will be asked to enter the name for your outside access. Let's call it remote.hosle.net. (Hosle is a nice place outside Oslo in Norway). The wizard will among other things create the necessary SAN certificate for you Now you need to transfer your domain to DynDNS (most routers support this option). When the transfer is done, create an A record in the DynDNS DNS server, for instance mx.hosle.net. Create a CNAME (alias): remote.hosle.net. You're done. Now, your ISP might put some hurdles in your way, such as not allowing you to receive on port tcp/25, perhaps not use their SMTP server as a smart host. DynDNS has all types of solution to these problems: http://www.dyndnscommunity.com/forum/viewtopic.php?f=12&t=829 Take also a look at this thread: http://social.technet.microsoft.com/Forums/en-US/exchangesvr3rdpartyapps/thread/ebb10028-6308-4cd4-906a-aa5166069093 Please come back with further questions if something is unclear.

I have taken the cowards way out. After speaking to TalkTalk, who can't offer fixed IP at present, I found out it is only 70 to cancel, so I am going back to BT and will use their business offering (I recommend it to my customers and so I suppose I should use it myself). Trouble is when I moved my line to TT they LLU'd it. This means I have to move it back to BT first and can only then order broadband for it, so I will be without ADSL for about 5 days. I have my iphone to surf and email on so its not the end of the world, and there are wifi cafes near me so I can get online if required.Sorry to wimp out, but I didn't want to risk my business emails on dyndns when I do not know how robust it is. It's the straight and narrow for me from now on....BTW - thanks for the advice.
