[K12OSN] Can send, but not receive, emails from clients

[Carl Keil]

Hi Folks,

I mentioned this a while back, but after a complete fresh upgrade 
(install on new server) to K12ltsp 5.0.0 I'm still having this crazy 
problem.

I can set up my own personal email account in Thunderbird on the 
client.  I can send email, but I can't receive it.  I'm using all the 
same settings that work on my Win2K workstation on the same LAN and it 
doesn't work.  I've tried dropping the firewall completely on the 
k12ltsp box and it still doesn't work.  Has anyone heard of this problem 
or know how to fix it?  One thing that's really wierd with T-Bird is 
that there's not really any clear place to put the password and it never 
asks me for one when I try to check my email.  There's no error message 
or anything.  What's a procedure to troubleshoot this.  I've tried other 
email programs (2 of them) on the client and I have the same problem.  
Does my login password on the client need to be the same as the login 
for my email server? 

I tried calling my ISP for tech support, linux is not supported and thin 
clients are literally unheard of. 

This is driving me crazy AND making me feel like an idiot.  Does anyone 
have any ideas?
