The whitelisted spammers are hammering my hotmail account so badly I can no longer use it. I'm getting spam in my inbox for viagra and all those other great keywords that obviously make the mail spam and these messages are immune to Hotmail's junkmail filters altogether.

As for Gmail, do you really trust a company to look after all of that data in your gmail account and not wrongly share it or give the wrong people access to it?

I like keeping all of my information as close to my chest as possible - on my server at my house.

No I am not sitting in a rocking chair on my front porch with a shotgun on my lap. But I'm seriously considering it.
