If you’re mail server is cracked then everything you’re sending out is exposed. Anything you put in your emails can be read by someone. They could set it up so that everything you send gets forwarded to them. If you run a business you can only imagine what a nightmare that would be. Company secrets and personal information of your employees and clients would slip out into the world and you would no doubt get into some serious trouble. That’s why you need a secure mail server and you need one now.
There are lots of options for a secure mail server so you need to make sure that you do your research. You can find free versions and you can pay for something a little more sophisticated. It all depends on what you need. If you’re a big company then chances are good you’ll have someone hammering at your security more often so you’ll want something extra super secure. If you’re a small company then you probably don’t need to spend a lot of cash on a secure mail server because few people will be trying to get at what you’re sending out.
