Qmail: An Alternative to Sendmail
qmail has quietly become one of the most widely used
applications on the Internet today. It's powerful enough to
handle mail for systems with millions of users--Like Yahoo!
Mail and Hotmail, while remaining compact and manageable
enough for the smallest Unix- and Linux-based PC systems.
Its component design makes it easy to
extend and customize
while keeping its key functions secure, so it's no wonder
that adoption of qmail continues at a rapid pace.
The downside? Apparently none. Except that qmail's unique
design can be disorienting to those familiar with other
popular MTAs (Mail Transfer Agents). If you're coming from
sendmail, for instance, you might have trouble recasting
your problems and solutions in qmail terms. qmail first
helps you establish a "qmail frame of mind," then explores
the installation, configuration, administration, and
extension of this powerful MTA. Whether you're installing
from scratch or managing mailing lists with thousands of
users, qmail provides detailed information about how to make
qmail do precisely what you want
qmail concentrates on common tasks like moving a sendmail
setup to qmail, or setting up a "POP toaster," a system that
provides mail service to a large number of users on other
computers sending and retrieving mail remotely. The book
also fills crucial gaps in existing documentation, detailing
exactly what the core qmail software does.
Topics covered include:
Installation and configuration, including patching qmail
Moving from sendmail to qmail
Handling locally and remotely originated messages
Managing virtual domains
Logging qmail activity
Tuning qmail performance
Running multiple copies of qmail on the same computer
Mailing list setup and management
Integrating the qmail MTA with POP and IMAP delivery
Filtering out spam and viruses
If you need to manage mailing lists, large volumes of mail,
or simply find sendmail and other MTAs too complicated,
qmail may be exactly what's called for. Our new guide,
qmail, will provide the guidance you need to build an email
infrastructure that performs well, makes sense, and is easy
to maintain.
