IMHO M2 is a great Mail, Newsgroups & + client
- Use it since back in 2001 (win98 then w2k until early 2003)
- Have keep it while migrating to Linux (Mandrake 8-9-10)
- Still used it when migration was done (2003-2005)
- Still use it while having switched to Arch linux on desktop & laptop (rsync -avz --delete does the trick beetween my machines)

Now have 6 accounts, ~200 contacts & a few dozains of thousand of emails on it.
It simply rocks :D

Eudora will be going open source. Free as in beer AND speech.
Will be for Windows, Mac, and Linux.
They want user feedback on what everyone wants.

We use Claws (ex Sylpheed-Claws).

Opera is not open-source. By using Opera you are abandoning your freedom. Use FLOSS clients like Evolution and Thunderbird.

I use Opera too.

Outlook XP via CrossOver 4.1

I know, I know. I need to let go...

I use Opera's M2 mail client

I use the Mozilla Suite, as I find it more convenient to have it in the same package. Maybe it is oldfashioned, nut then again I have been using e-mail and the WEB since 1990.

One of the reasons I haven't yet actually switched to Linux from Windoze is that all the email clients I've tried are trying to be Outlook clones. Outlook's interface drives me crazy and just doesn't work for the way I work.

What works for me is Eudora. I love the buttons across the bottom for each open folder. Mostly I love that when new mail arrives it is automatically routed to the apprpropriate folder by the rules that I've set up and this folder is then placed on the button bar so that I know that new mail has been placed there. This allows me to quickly know I have new mail and to decide if I want to read it immediately. If I'd like to read it later I can leave the button there to remind me I have unread mail in that folder. If I want the mail around, but don't want to read it I can just close the folder and the messages are still there for me to search when I want something.

I haven't tried Eudora yet under WINE. I'm hoping it works because none of the true Linux email clients I've tried come close to what works for me.

Just switched to Mozilla Messenger (on OS X) but loved the look of Evolution.
At work gotta use Windows/GroupWise. Webbased mail is good but I like knowing where my messages are. Used HordeIMP exclusively for a while.
Now I have too many web-based email addresses!

Yo uso Mozilla Thunderbird y bajo mis correos de Yahoo y Gmail!!, =)

I voted KMail, but I actually divide 50/50 between KMail and Mutt (depends upon whether I am running at home or remotely). It would be noce to allow split votes.

I use yahoo.

I use Groupwise by Novell. It works really well if your company uses a Groupwise email system.

I use Opera 7.60P4 (preview version) on one machine and Opera 8.0B2
(beta version) on another machine. I even use Opera 8.0B2 on a windblows
box.

I use Opera Mail client. it's cool

I have an IMAP server and use various mail clients (because I like the flexibility), my most popular being Kmail and squirrelmail (webbase mail client). I also use mozilla messenger/thunderbird/mailx.

How odd. One would think there would be a larger response to such a good poll quesiton.

I'm a Kmail fan myself. Have loved it since it's for release with KDE1x :) Very good integration into the DE. Snappy response, even on old computers like this one. Great crypto support, along with KDE in general. Simple to set up. Love the auto-discover thingy that will detect best server settings--that is just neat!

Hopefully, we'll see Mozilla put out a good Email client. Still, I was a little surprised when Firefox 1.0 couldn't import my Konqueror bookmarks :(

I use plain old web based email via Yahoo. Have for years. It simply works.

I use Opera's M2 mail client

squirrelmail

web based email

emacs' rmail

I use Google's GMail

I like KMail for a number of reasons: 1. Message threading; 2. Kgpg integrates with KMail's address book; 3. Easy spam filtering with spam assassin (SuSE comes with excellent instructions on how to set up spam assassin with KMail); 4.. complete synchronization with my Palm Pilot. Much of these nice features have more to do with KDE and SuSE than KMail itself.
