DomainKeys Identified Mail (DKIM) is a method for email authentication that allows an organization to take responsibility for a message it has sent in a way that can be validated by a recipient. The technique is based on public-key cryptography: Responsibility is claimed by the signer by adding a digital signature to a message's header, the DKIM-Signature header field. The verifier recovers the signer's public key using the DNS, and then verifies that the signed parts have not been altered.

Procmail is a program available on all ACS machines which allows you to automatically process your email as it arrives into your account. You can sort, delete, forward, and store messages depending on their sender, their subject, or other characteristics. For example, you could have Procmail direct all messages from your friend at UC Berkeley into a folder called "berkeley". You could then read the messages in this folder at your leisure via webmail, or with Pine, Mutt, or another full-featured e-mail reader.
This article will show you how to read your email using Command Prompt (Windows), Terminal (Mac/Gnome), or Konsole (KDE). Using the Telnet client, you can read your emails through command-line entries. Here are the steps for getting connected and reading your emails through the IMAP protocol.
This book is designed to get you started with the Slackware Linux operating system. It's not meant to cover every single aspect of the distribution, but rather to show what it is capable of and give you a basic working knowledge of the system.
Although there already is an abundance of procmail material on the net, here are some of my own tips and observations. This tips page is a companion of my Foiling Spam with an Email Password System page. The items on this page are in no particular order.
The setup I have is a bastion host in a DMZ and an internal mail hub. The bastion host receives incoming mail from the Internet and relays it to the internal mail hub. It also receives outgoing mail from the mail hub and delivers it to the appropriate destination host. I did this using Sendmail 8.11.x, but it should be fairly easy to use these instructions on any 8.10+ version. by Jason Heiss
There are a lot of samples of URL encoder on Internet, but I find no one URL encoder which I can specify a destination charset for the URL encoded data. I'm working in Czech, so many times I need URL encode to windows-1250 or iso-8859-2 charsets. Within this sample, you can specify any characters in Unicode (utf-8) and destination charset and you will receive the unicode data URL Encoded.
