-Unix servers generally come with some kind of mail server installed. This is used to send mail generated by the system for log reports, error messages, etc... By default, it goes to the root account on the local server, but this requires a technician to log into each server and manually check mail. It is much better to have all mail forwarded to one or more e-mail accounts.+Unix servers generally come with some kind of mail server installed.

 Long ago, in a galaxy far, far away, we could set up a central mail server to simply relay all e-mail from any random server. We would set up the root user on each server to actually be an e-mail account on a centralized machine, then check that one account. Then, the spammers got involved, started using these //open relays// to send out junk mail, and we had to turn them off. Long ago, in a galaxy far, far away, we could set up a central mail server to simply relay all e-mail from any random server.
