I just wanted to provide an update to my problem here in case this is read down the road.
I looked at multiple email hosting services for businesses and ended up going with
www.webmail.us
I have NO affiliation with them, just a very, very satisfied customer.
Prior to moving to webmail, I was getting spam emails galore, one of which included a virus that shut my computer down (see first post). Now, I get maybe one spam email a day, which is down quite a bit.
Here's my stats from the last month of service:
As you can see, in just the last 30 days I had 694 spam messages and 179 DHA's as well. I received 177 emails that I wanted and sent 143 emails. Needless to say, it was very frustrating when you get spam that is over 3 times what you are actually wanting to receive.
Anyways, these guys are good, know their stuff and the pricing is very reasonable. I only needed their minimum plan and it's a whole 60 bucks a year for 5 email addresses.
