This document covers how I have set up my Linux box to work as a Mail Server. The details will be specific to Arch Linux, but it will be be general enough for any *nix distribution if you have a knowledge of installing software packages, finding the location of configuration files, and starting/stoping services..

My goals in creating this mail system are to have all of my mail, from various email accounts, stored locally on my machine so I can access it anytime via SSH, the web, or imap. I wanted all of my mail delivered to my local user account and I wanted the spam to be sucked out and launched into space.

In Xterm's emulate of the vt100 terminal it sends '^H' (0x08) when the backspace key is hit, "\e[3~" when the delete key is hit, and '^H' (0x08) when ctrl-h is hit. Some programs, such as Emacs, want to use '^H' (0x08) for commands other than delete. To work around this problem the key-map in Emacs either has to be changed to accept '^H' as delete left or Xterm should send '^?' to delete to the left and tty should be told to expect '^?' as meaning delete left. The solutions shown in the next section address changing Emacs key-map, getting Xterm to send the different key codes, and setting stty's variables.
