I use Claws Mail. Its lightweight (in terms of memory usage) and after some getting-used-to very easy to use. Its gratis and open source runs on Linux and Windows (and many *nix see the downloads page).

It can connect to Pop3 and IMAP accounts and has build in SSL abilities to encrypt your connection to the server.

If you hit answer on an email it will respond with the corresponding email account. This means the "account where the mail came in" (instead of the "To" Field) so, if you are on mailing lists, this works as well.

It has no statistics plugin I know of.
It has Desktop notification in multiple flavors.

The Interface is good, but at times you need some extra thinking until you got used to it. But it will warn you every time thats the case (and you do something you most likely don't want to). I felt very comfortable with it after about two weeks and in fact would love to see more tools using their approach by now.

It can also PGP, S-MIME has two spam filters you can chose from (Bogofilter and Spam Assassin. I use Bogofilter and am happy with it). You can have Filter rules to let your mail be automatically sorted. Of course it has multiple Address books, Color Labels and lots of other features (a full list has been composed here.)

I'd add a screenshot of my own, but thats too personal :) Have one from their site:


You can customize the looks of it either through options or themes. With a tool (csv2addressbook.pl from the Tools site) you can import your G-Mail address book (I haven't tried that myself).

I use Claws mail since 2007.

When I disable an active script in unity, will it be disabled then and there, or will it only be disabled at the end of the frame?

For example, if I disable a certain script from within a "OnCollisionEnter" event method, will the "disabled" script still perform it's Update method for this frame?
