Kinda OT: Email clients and Email Management

Hi Ya'll,

I know that there are, to me, seems like A LOT of email clients for the 
linux world.

And It's getting harder and harder for me to hop around and try new 
email clients out when they come out being a..........GET READY TO 
CRINGE..... POP3 user.

Last week I tried TDE ( Trinity Desktop ) on Debian. and decided to give 
KMAIL a try... Big mistake... Importing my email into KMAIL caused the 
emails names to be changed from numbers ( because I used Claws before) 
to this weird string of letters and numbers. Therefore, I could not 
import my email back to CLAWS since I gave up and returned to Fedora and 
Gnome 3.

I plan on staying with Fedora and Gnome 3.

I thought about making the change to IMAP, but old habits die hard. I 
find myself when I set up or try a new email client, I wind up setting 
it up as POP3...

So I am just curious if there is any POP users still out there

And what are some pros and cons switching to IMAP?

And what program do you use on Fedora for your email?

Thanks,
Chris
