DRAC is a daemon that dynamically updates a relay authorization map for sendmail. It provides a way to allow legitimate users to relay mail through an SMTP server, while still preventing others from using it as a spam relay. User's IP addresses are added to the map immediately after they have authenticated to the POP or IMAP server. By default, map entries expire after 30 minutes, but can be renewed by additional authentication. Periodically checking mail on a POP server is sufficient to do this. The POP and SMTP servers can be on different hosts.\n\nFor more information about DRAC, see the following topics.

Help Create an Email Charter!
Houston, we have a problem.
We all love the power of email connecting people across continents. But... we're drowning in it.
Every year it gets a little worse. To the point where we can get trapped spending most of our working week simply handling the contents of our in-boxes. 
And in doing so, we're making the problem worse.  Every reply, every cc, creates new work for our friends and colleagues.  
We need to figure out a better way. 
But how?
Here is the key cause of this problem:
The total time taken to respond to an email is often MORE than the time it took to create it.    
Because even though it's quicker to read than to write, five other factors outweigh this:
- Emails often contain challenging, open-ended questions that can't rapidly be responded to
 - It's really easy to copy and paste extra text into emails. (Email creation time is almost the same. Reading time soars.)
- It's really easy to add links to other pages, or video (each capable of consuming copious gobbets of time)
- It's really easy to cc multiple people
- The act of processing an email consists of more than just reading.  There is a) scanning an in-box, b) deciding which ones to open, c) opening them, d) reading them e) deciding how to respond  f) responding  g) getting back into the flow of your other work.  
So the arrival of even a two-sentence email that is simply opened, read and deleted can take a minimum of 30-60 seconds out of your available cognitive time.  
This means that every hour someone spends writing and sending email, may well be extracting more than an hour of the world's available attention -- and generating a further hour or more of new email. That is not good.
It is in fact a potent 'tragedy of the commons'.  The commons in question here is the world's pool of attention.  Email makes it just a little too easy to grab a piece of that attention. The unintended consequence of all those little acts of grabbing is a giant rats nest of voracious demands on our time, energy and sanity.

MIMEDefang

MIMEDefang is an e-mail filtering tool that works with the Sendmail "Milter" library. MIMEDefang lets you express your filtering policies in Perl rather than C, making it quick and easy to filter or manipulate your mail.

MIMEDefang is mature software: The first version was released in 2000. It's also in use in thousands of installations.

MIMEDefang is under active development; it forms the basis of our CanIt commercial anti-spam product.

MIMEDefang is free software: It's released under the terms of the GNU General Public License. It runs under Linux, FreeBSD, Solaris and most other UNIX or UNIX-like systems.

"We are scientists, engineers, and developers drawn together by a shared vision of protecting civil liberties online. This is why we created ProtonMail, an easy to use secure email service with built-in end-to-end encryption and state of the art security features. Our goal is to build an internet that respects privacy and is secure against cyberattacks.

We are committed to developing and widely distributing the tools necessary to protect your data online. Our team combines deep mathematical and technical knowledge from the world's top research institutions with expertise in building easy to use user interfaces. Together, we are building the encrypted communication technologies of the future."

"There are several different approaches to building a distributed electronic mail infrastructure. Among them: shared file-system strategies, proprietary LAN-based protocols, the X.400 P7 protocol, and the Internet message access protocols. The purpose of this paper is to briefly consider the Internet-based protocols: POP (Post Office Protocol), DMSP (Distributed Mail System Protocol), and IMAP (Internet Message Access Protocol). Of the three, POP is the oldest and consequently the best known. DMSP is largely limited to a single application, PCMAIL, and is known primarily for its excellent support of "disconnected" operation. IMAP offers a superset of POP and DMSP capabilities, and provides good support for all three modes of remote mailbox access: offline, online, and disconnected. (See RFC-1733 for definitions.)"

"E-mail client supporting multiple accounts, POP3, IMAP and Push IMAP. Can do encryption if APG and/or OpenKeychain is installed -- depending on the version. Settings and account configurations can be exported so that they can be imported easily if you are switching packages/signatures: a file manager will need to be already installed to achieve this.
