RBVM Exim

Your VM can send mail through mailhost.vmsrv.redbrick.dcu.ie. You can use any MTA to do this, documentation for exim is just provided cause I like exim.

Debian/Ubuntu

The easiest way to configure on this is to use dpkg

 # apt-get install exim4-daemon-light
 # dpkg-reconfigure exim4-config

Set the name to 'whatever you named your vm'.vm.redbrick.dcu.ie

It should only listen on localhost

Mail should not be accepted for any destinations

No need to change the visble domain name

Route all mail to mailhost.vmsrv.redbrick.dcu.ie

DNS queries can be left at the default, and the configuration does not need to be split to small files

Other Systems

• Install Exim from somewhere.
• Go through the config file and fill out primary_hostname as name.vm.redbrick.dcu.ie
• Unless you know what you're doing don't touch the acl section.
• Delete the Routers & Transports section
• Put this in it's place:
