Network Computing: Tutorial -- Procmail: A One-size-fits-all mail processor

"This article shows Unix system administrators how they can enhance their e-mail setup by installing procmail, a general-purpose mail processing program for all brands of Unix. I will use Linux as an example system, but what I say should apply to to other Unixes.

"The simplest way in which procmail can be used is as a drop-in replacement for the local mailer. This entails mail delivry as normal, plus extra processing if a .procmailrc file is present in the home directory of the recipient.

"You may wish to store mail in the recipient's home directory, rather than in the traditional /usr/spool/mail. This has some obvious advantages:

• "Mail is subject to the user's quota limitations. there is often more room on the home partition(s) than on /usr/mail.
• "The quota limitations also apply to /usr/spool/mail or /usr/mail if procmail does the delivery."
