[kwlug disc.] Email problems

[Insurance Squared Inc.]

I have sporadic problems with getting my email off of my server.  
Running Linux (though it's happening on all the machines on my home 
network) through a home router, through a dsl modem and over to my 
Mandrake server.

What happens is when I use thunderbird to download my email from my 
account on my server, it sits and spins for quite a while.  Then it 
seems to connect and download fine.  Uploading emails is instant. Web 
traffic is instant as well.  It's only downloading email from my server 
to all the machines on my home network that has this problem.

Also it seems sporadic.  It's been doing it for a few days now nonstop.  
Prior to that it hadn't done it in a few months.  It almost acts like 
it's having nameserver problems like where it waits for one nameserver 
and times out to go to the second.  But I'm not having any ns problems.

My email client says it's connected immediately, but I don't see the 
connection in the logs on the server until after the delay.  It's not my 
end computer since it happens on different email accounts on different 
computers at home here.

I've powered down and up my router and modem.  No change.

I'm stumped - any thoughts on how to diagnose this further?
