We are a small nonprofit who does almost everything in house. I know almost nothing about networking, however we are having a problem that I believe is easily fixed.
We are using MS Exchange Server 2003 SBS on site. We have a hosted domain at GoDaddy as well as their email plans. As I understand it (which is debatable), our email is routed through Exchange Server via a POP3 account. We can log into our mail using the Exchange Server (our IP address/exchange) or through GoDaddy's site.
A few years ago, we had trouble sending more than 250 emails a day through GoDaddy. It didn't happen that often that we reached that quote, but when we did, it was an issue. So, our old IT guy created an SMTP connector that sent our email through his server at 1and1.com. Unfortunately, that server is spammy and now we cannot send to certain addresses as we are flagged as spam. I am certain that is the problem, because we I send an email through GoDaddy, that IP address is fine and the mail sends, but when I send it through Exchange, it is delayed for about three days and then returned claiming "too much spam." I checked out both addresses at CBL and indeed that is what I found.
So, my question is, how can I change (or delete) the SMTP connector to route back to GoDaddy? I have some idea, but don't want to try something that will take down my coworker's email.
