Here are our stats after being online with Katharion for a full week.

I had to chuckle a little when I realized that Katharion is handling more mail for Parimeter in a single day than it is for us in an entire week. I also noticed that our spam-to-legit email ratio is pretty low. Interesting… maybe we have a bunch of users that are getting email feeds off of forums or something.
I’m still very impressed with how much garbage Katharion is keeping off of our email server. This not only saves our users time and frustration from sifting through their inboxes, but over time we’ll save quite a hunk of bandwidth as well. Right now we only have a non-line-of-sight wireless connection, so that hunk of bandwidth is pretty valuable. :-) (That in itself is another story for another time).
So far so good! I’ve yet to hear any ill remarks about Katharion’s services, and judging from our experiences, it doesn’t yet look like there’s a good reason not to go with them.Â
