I've sent you the information. I'm no expert in these matters, but it looks as though there was some sort of DNS problem en route, (seemingly with mindspring.com?) or maybe my mail server has mindspring.com 'blacklisted' for some reason?
I've done a few tests and I can send and receive mails from other domains, so I think it may just be something to do with mindspring.com or your mail server?
If anyone else has any problems getting mails to me, please do post something here, and I'll get it investigated.
Thanks,
Martin.
