I liked everything about this program with one exception it was way to much work! It took too long as well which is hard when using other programs (as there usually are multiple windows open). We ran into issues in that we had an old server set up but wanted our new sites/email addresses setup quickly so they could operate before people came back from vacation or after Christmas Break / Easter break etc.. That's really all just minor things though if done correctly you can solve problems very easy by having them move their emails forward 1 week vs 4 weeks later once everyone returned - solved problem instantly!! I like how easy it is to set up an account with them as well! They are very helpful when you need support or want some one-on -one time help setting things down correctly (like DNS). If your looking at getting something that's reliable then this would be my first suggestion out of all others in terms if reliability/uptime etc.. For starters its cheap compared against other companies who offer more options but not necessarily cheaper than what they have available here!!
