There's no way my outlook signature would have ANY bearing my my email address during registration. But let's just drop it, shall we?
What I meant was, the mail server might filter based on content, as well (although a filter that excludes a e-mail as spam because it contains a url is a bit overzealous, so I doubt that's the case, anyway)
I used to use IE all the time myself... but I think, that was around the time of IE 5.5. My initial experience with Firefox was awful- my PC was a bit underpowered for it's cache mechanism, since it only had around 128MB of RAM... even today I am still suffering from the same old habits of having teensy bits of RAM- even though I now have 8GB to play with.
