The Book of IMAP: Building a Mail Server with Courier & Cyrus
IMAP (the Internet Message Access Protocol) allows clients
to access their email on a remote server, whether from the
office, a remote location, or a cell phone or other device.
IMAP is powerful and flexible, but it's also complicated to
set up; it's more difficult to implement than POP3 and more
error-prone for both client
and server.
The Book of IMAP offers a detailed introduction to IMAP and
POP3, the two protocols that govern all modern mail servers
and clients. You'll learn how the protocols work as well as
how to install, configure, and maintain the two most popular
open source mail systems, Courier and Cyrus.
Authors Peer Heinlein and Peer Hartleben have set up
hundreds of mail servers and offer practical hints about
troubleshooting errors, migration, filesystem tuning,
cluster setups, and password security that will help you
extricate yourself from all sorts of tricky situations.
You'll also learn how to:
Create and use shared folders, virtual domains, and user
quotas
Authenticate user data with PAM, MySQL, PostgreSQL, and LDAP
Handle heavy traffic with load balancers and proxies
Use built-in tools for server analysis, maintenance, and
repairs
Implement complementary webmail clients like Squirrelmail
and Horde/IMP
Set up and use the Sieve email filter
Thoroughly commented references to the POP and IMAP
protocols round out the book, making The Book of IMAP an
essential resource for even the most experienced system
administrators.
