Debian Etch SMTP relay server using exim4
I'm having trouble setting up my server to send email.
I have set up my server using exim4, courier-imap, and fetchmail.
Currently it downloads email from my ISP and other email accounts that I have and then hosts it as an IMAP server so that all my clients can see the same emails according to the user.
I would like to do the opposite however and relay email messages sent out from my clients through my ISP's SMTP server but I can't even get the server to simply send email.
I've searched everywhere for an example or howto and found nothing, then I posted in the Debian forum but no-one replied.
If anyone has any suggestions I would be greatfull, it might be that I am missing something very basic here.
I don't have a domain name but I do have a static IP!
Many thanks in advance
