Google apps for your domain
andre
I have recently registered with Google apps for your domain . I was surprised with the speed by which they processed my application and gave me a go ahead.
So now I can create e-mail users in my own domain and have a full-fledged web interface - and all for free! Addresses are something like
andre@baryudin.com
or any number of other e-mail addresses I can think about - for any purpose, including spam filtering and mail sorting. Google chat and Calendar are available as well.
