Small Business Server Using Exchange and POP3 question

oriontech2 asked
Last Modified: 2010-04-19
Here is the scenario:

I have a client in a small business server 2003 enviornment using outlook 2003 to receive their email via pop3 from a third party.
So the mx record is pointing to mail.businessname.com and the A record is pointing to hostingprovider.com's ip. The hosting provider is setup to receive email for businessname.com. Everything on that end is working as normal.

Right now the local sbs 2003 domain dns is setup as businessname.local according to small business server general standards.

One of our problems is that when we try to send email out through the exchange portion of the server we get kickbacks from the server saying delivery failure. Because outlook 2003 uses the "exchange" account as the default sending account. I know there is a registry fix to correct the problem but I do not want to have to use that method. See, sometimes users open exchange and forget to swtich to their pop3 account as default sending account. If they forget to do that then their email gets kicked back.

I dont want to have to use any hacks to solve this problem. From my understanding this is a known issue with SBS2003. Maybe there is a different way to set this up or use .com instead of .local as the domain?

Also, for redundancy, should I just setup 2 mx records 1 pointing to our server (primary) and direct all mail to the sbs server directly, and 1 pointing to the 3rd party email hosting (secondary) just in case our sbs goes down? (we live in FL and we have a lot of storms so I want maximum uptime without having to babysit issues)

and if I do it this way will it solve the problem above?
