[TriLUG] debian exim4 + courier-imap: can read & receive but not send

[Jason Tower]

this is purely a smtp issue, courier has nothing whatsoever to do with 
it.  smtp is used to send mail, courier to retrieve it.

assuming exim is anything like postfix, you need to tell it what hosts 
are allowed to relay mail.  this might be any hosts on the same subnet 
as the mail server, or a specific set of IPs, or whatever.  it sounds 
like the default setting is to only allow localhost to relay mail, 
which is why it works from the command line but not your workstation.  
in postfix this would be the mynetworks or mynetworks_style parameter, 
i don't know what the exim equivalent is though.
