exim4

exim4 is an MTA. The current plan is to use exim4-daemon-light as the MTA on all the Configured Workstations.

Here's dkg installing exim4 on metis (note that once the Mail Server is set up, the CWs should be configured to send mail through that server as a "smarthost"):

[dkg@metis ~]$ sudo apt-get install exim4 mailx

Configuring Exim v4 (exim4-config)
----------------------------------

Select the configuration type that best meets your needs.

Systems with dynamic IP addresses, including dialup systems, should generally be configured to send outgoing mail to another machine, called a "smart host" for 
delivery. You can choose to receive mail on such a system; or to have no local mail delivery, except mail for root and postmaster.

  1. internet site; mail is sent and received directly using SMTP  3. mail sent by smarthost; no local mail  5. manually convert from handcrafted Exim v3 configuration
  2. mail sent by smarthost; received via SMTP or fetchmail        4. local delivery only; not on a network  6. no configuration at this time

General type of mail configuration: 1
