Steve,
To be hones, I'm a bit turned off by MIE. I emailed them 2 days ago then yesterday I used the web form because I hadn't heard from them. I still haven't heard MIE. Are they even still around? Their website looks to not have been updated for a while now.
Thanks for your patience, we are going to look at the firewall again. We have sent 3 test messages, they came through...we have not seen yours.
(getting close to putting a fork in this system)
