I really have to wonder, does the world really need another such client? Here is a bunch of them:
- Roundcube – Written in PHP with a moderm AJAX UI.
- The Horde Project – Not only provides E-Mail, but a full groupware suit.
- Zimbra – Not only provides a client but also a full server that can replace Microsoft Excange.
- SquirrlMail – Includes a rather old style UI, but seems to be very popular. Most web hosting providers support installing it directly with their site management tools.
- Mailr – Not very pretty, but written with Ruby On Rails, if you don’t want to run PHP.
- And many, many, more.
I’ve been running my own mail sever for years. In my view, that is where the bigger problems are, the constant flood of spam and other E-Mail attacks, seems to have led most internet service providers to block all E-Mail sent from anyone who doesn’t look like a large service provider. When running my own server I’d often find out that my mail get rejected unless I relay it through such a provider.
