Your backend should discover IPs making attempts and block them. Should also be systems to sense outbound spam and peculiar traffic patterns and block or rate limit those.

That’s 99% of what we do.

We have a few (maybe 10) remaining aside from our in-house emails. These 10 customers are not really profitable due to the amount of time that we spend dealing with email issues every year. I would never even consider going back to providing email, and we are considering cancelling these ten.

We also backup everything on a daily basis, pricing starts at 2 bucks a mailbox but goes down from there as the scale increases. We offer secure webmail, secure POP/IMAP as well as SPF and DMARK if you are so inclined to do so. Remote administration and simple migration. All of our pricing is here . https://www.linktechs.net/productcart/pc/viewcontent.asp?idpage=47 in case someone wanted to know or wished us to host it. J Just a FYI.

I thought nobody would pay that much. I found they would happily do it. I kept raising it. They finally started fleeing when i required $20 a month paid annually.

Though maybe we should, we set it at 5 bucks a box per month with required annual payment if you want to keep your email after leaving our service. Figured that would get them to go away, but a suprising number keep it. Its pure cash, like people who still have dialup customers that churn cash with zero support each month.
