I signed up for a hotmail account yesterday because I knew in July MS was going to up the storage and I wanted to see what all they changed. my Junk Mail folder is already full of Junk Mail. And one of them is a bunch of undeliverables because someone already spoofed my account when sending junk mail.
That is crap! Hotmail sucks really bad in this regard. What did I expect? Well, at least to go 1 day without any junk mail. I have had a gmail account for about 3 weeks and not 1 single piece of junk mail have I recieved.
I used to have a Hotmail account, but gave up after the huge level of spam - I once got 999 emails from the same company in one day. I'll probably give gmail a go when its ready, but I expect that spam is just a part of emailing these days - unless you've got a very good filter, there's probably not much that can be done about it.
Yahoo gave me an account when they took over egroups where I was subscribed to some mailing lists but I never used it.
Hotmail generates about a hundred pieces of spam a week, not that bad considering I get that many or more a day on my real account (I use hotmail only when someone wants an email address but I don't want them to have one).
