sendmail

About

Sendmail is a free/open-source email server that handles both relay and delivery. The documentation is very detailed but also unclear on many critical points.

Notes

• /features are invoked and configured in the sendmail.mc file
• /macros are used in various places
• /procmail: still trying to figure out how to get these to work together
