Set Up Mail Server

~~TASK:Garrett Koller?~~ Set up john to be an email server so that condor-admin@condor.cs.wlu.edu can receive mail (and just forward it to me).

• Configure mail rerouting so that outgoing mail will be rerouted to the sendmail service on terras. That way, the sendmail service doesn't have to run all the time.
• Set up basic email server for condor@condor.cs.wlu.edu to send Condor mail and condor-admin@condor.cs.wlu.edu to receive mail (and forward to me).
• Change public email address to be condor-admin@condor.cs.wlu.edu in mail map file, wiki homepage, Condor configuration file, and installation script.
