Cyberforces are conspiring to cause further problems and I've exhausted all possible avenues of being able to fix it for now. I'm getting e-mail via the blog here from people who are wondering why they never heard from me via the regular channel. The answer is that I have no idea. It's not ending up as junk, the filter is set to medium to try and block as many viagra/stock market messages as possible and it doesn't seem to be bouncing.
If anybody out there knows what the cause and indeed cure might be then please, clue me in.
