I use zoho docs for a lot of stuff already, which is why I tried Zoho Mail. Well, I wouldn't normally use it very much, as I like my personal gmail account very much. However, when I got my wordpress.com website going with a custom domain, I wanted to get an email address with that domain attached. However, if you go through gmail you have to pay for that. I finally found out that Zoho Mail allows this. However, it was very difficult. I don't even remember how i did it. Nevertheless, my Mail.app client sends and receives mail with my custom domain email address, and somehow it is working through zoho mail.
