Email

Introduction

Email is still the #1 app on the internet.

I list below free and open source solutions to email. You need not consider the closed source alternatives. They are dramatically inferior in a number of ways.

Hosted

• Google Hosted: Have Google serve your email need.

Other hosting providers will provide one or more of the free options I list below.

Email Servers

• Sendmail: Sendmail is the 500lb gorilla in email. There are other systems, but sendmail remains the most relied on tool to send email.
• postfix
• qmail
• sSMTP

Email Access Protocols

• POP
• IMAP
• dovecot: Serves the above

Webmail

• SquirrelMail
• Round Cube
• Internet Messaging Program (IMP)
• Horde

Email Apps

• Thunderbird
• KMail
• Mutt
• mail (unix command)

Helper Programs

• fetchmail: Fetches email and delivers it for you.
• UP IMAP Proxy: Allows non-stateful protocols (like HTTP, which web-based email programs use) to maintain stateful connections to an IMAP host.
• mailman: Manage mailing lists locally.
