I decided to give this a try and so far I am having a couple of problems...
1. I have tried to add an email address on frontiernet.net with no luck, the system tells me that one email has been sent to mx.frontiernet.net but I never receive it.
2. I added a juno.com account to my mailhosts and not it thinks my spamcop email forwards to Juno. And also my SpamCop mailhost shows my juno.com email instead of my spamcop.net one. I will try to re-register my spamcop.net email to see if that fixes this problem.
I will continue playing with this and report later...
