Network email setup

[jb701@uku.co.uk]

First of all many thanks to everyone for the answers to a previous post 
about getmail and exim - I am now getting there. 

I am using sarge on a 486 thinkpad, it now successfully connects to the web 
and sends and receives email using exim and getmail.  Mail between users is 
delivered locally. 

Now I want to be able to send messages between this one and another machine. 
I know how to telnet from one to the other and send email, but that's not 
what I want to do. 

I have tried but failed so far.  I have the same user names set up on the 
two machines, but different host names.  When I send from joe@fireball to 
joe@thinkpad, the mail is delivered to joe@fireball. 

I changed exim.conf on "fireball" and now exim -bp reports mail held in the 
queue - but it still doesn't get sent. 

Grateful for advice.  I have been looking at exim documentation and googling 
for relevant things but not found anything that explains it is terms I can 
understand. 

I am using exim, not exim4.  If this is more appropriately asked elsewhere, 
please let me know. 

Regards 

- Joe
