Exchange server in home office using 1and1
Posted on 2010-09-17
I'm setting up an Exchange server (2003) in my home office. My domain name is registered at 1add1.com. I can't seem to get the A and MX records right at 1and1.
This is what I'm working with. Some of it could be wrong or completely unnecessary, (like the subdomain with the name of my server) in misguided attempts to get it right.
I think there are two things I'm not getting right, but there might be four. The two are the A and MX records for systems-that-work.com, and the other two might be A and MX records for stw-server.systems-that-work.com if in fact I need this subdomain at all. I confess to still being mystified about exactly how a message to firstname.lastname@example.org finds its way to my Exchange server.
These are the following things related to my environment that I have to work with.
I have tried several of them but none seem to work.
Comcast is my ISP, and I am using a Linksys router.
My router reports the following on the Status page:
IP address: 184.108.40.206
Default Gateway: 220.127.116.11
My 1and1 domain name is systems-that-work.com. I have created a subdomain on 1and1,
My server's name is stw-server
My Windows domain name is systemsthatwork.local
My server's internal IP address is 192.168.1.110
I've tried several things and right now my settings at 1and1 are:
A record - 18.104.22.168
MX record - stw-server.systems-that-work.com
but I'm not receiving any email messages, so these must be wrong.
In addition to knowing what to enter on 1and1 for the A and MX records, can you
tell me if there is something I have to enter in the DNS settings on my server? I don't think there is, based on looking at the DNS settings on another Exchange server I manage (but which was set up for me and for which someone else is managing the A and MX records) This other server seems to have no DNS entries other than the internal IP addresses in the 192.168 range.
And as a point of information, does it take 24 hours for any change I make to my domain name, and/or my A and MX records at 1ad1 to take effect? Or did that 24-hour period for information to proliferate throughout the DNS system apply only to the initial creation of systems-that-work.com as an address registered at 1and1? 24 hours to register each change sure makes it take a while to get it right.
As you can see, I'm floundering here. This is probably dirt simple to hundreds of people who understand this, but I don't yet. Any help is much appreciated.
Thanks, Ron Hicks
