Mail client for windows

Hi all!

Still looking for a light footprint, fast email client under windows, I have done some googling and here are what I have found:

• i.scribe / in.scribe. It seems to be efficient, light and still in development. The free version, i.scribe, can only support one account. I have not achieved to configure gmail using IMAP protocol. So wait for another update.
• Becky. It seems very efficient, light, powerful. But it is 40$. You can try it for free for 30 days.
• Mulberry. It doesn't seem to be still in development. Open source, light and efficient email client. It fails in fetching all my email from my gmail account. But it is very fast! There is a nice review about it there
• The Bat!. It seems as good as Becky.
• sylpheed. I'm using this one daily. It is light with many features, but to me it is slow on windows (v2.6.0). I will install the version 3.1 this week end. UPDATE: i have moved to the 3.1 version. It is as light as usual, works, and maybe a little bit faster.
• Alpine mail, a full CLI mail client.
• Mahogany mail, last realase august 2006. Not supported : PGP.
si.mail. Not supported : IMAP, PGP.
• an interesting service to secure and follow email use : opolis
