Linux Bumpyputer 3.8.0-32-generic #47-Ubuntu SMP Tue Oct 1 22:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Description: Ubuntu 13.04
Release: 13.04
Codename: raring

Mail Program: Kmail (Latest Version)
I am finding the KMail Documentation very confusing because it should be more explicit for newbies like me.
Problem: Unable to receive mail Can send mail OK.

I followed these instructions:
Gmail Settings:
Enable IMAP in your Gmail settings
1. Sign in to Gmail.
2. Click the gear in the top right.
3. Select Settings.
4. Click Forwarding and POP/IMAP.
5. Select Enable IMAP.
6. Click Save Changes.
Incoming Mail (IMAP) Server - Requires SSL
imap.gmail.com
Port: 993
Requires SSL:Yes
Outgoing Mail (SMTP) Server - Requires TLS
smtp.gmail.com
Port: 465 or 587
Requires SSL: Yes
Requires authentication: Yes
Use same settings as incoming mail server
Full Name or Display Name: [your name]
Account Name or User Name: your full Gmail address (bumpysax@gmail.com).
Google Apps users, please enter username@your_domain.com
Email address: your full Gmail address (bumpysax@gmail.com)
Google Apps users, please enter username@your_domain.com
My Question: What is a “Google Apps” user? Since I use Google GMail, does that make me one?
Password: my Gmail password
I would be very grateful for any constructive help on this topic.

In your IMAP settings your username is your full email address. everything else appears to be fine

Thanks for the link!
Followed instructions at http://userbase.kde.org/Working_with_GMail
My Kontact : Version 4.11.2
Opened Kontact..
Click on Mail in the left vertical navigation bar. This brings you to the KMail part of Kontact.
To set up the forwarding options, go to: Settings -> Configure KMail.
According to the instructions:
The first step is to create a basic identify, this is to separate multiple accounts in the future, if you have them.
Can't do this – Kmail pops up! No way to create a “basic identity”
What now?

When setting up your imap account select clear text instead of plain authentication method. As shown in the following screen image.
