SquirrelMail in Debian
SquirrelMail is a GPL Webmail project, with aims to be complete but not have high requirements on server or client (browser). See http://www.squirrelmail.org.
This page contains some notes about SquirrelMail specific to the Debian packaging.
The following versions are available:
stable: the version in Stable is in many cases the best version to use; it may be some bug fixes behind upstream, but it works and is fully security supported. Get it by running apt-get install squirrelmail on your stable system. more info
testing/unstable: the version(s) in testing and unstable track the upstream stable releases; upstream normally only fixes bugs in this line, or adds very limited enhancements. If you want to use this, apt-get install it on a testing/unstable system. Mostly it will also be installable on stable, but this does not have guarantees. more info
experimental: here we package upstream released development series. These are not normally to be used in production, but serve as test releases. more info
backports.org: at the unofficial Backports repository, we're packaging the latest SquirrelMail upstream stable release, but packaged specifically for stable. See their website for information on how to acquire it.
The translations are packaged separately in the 'squirrelmail-locales' package. Install it if your users want their interfaces in something other than English. more info
You need to have the locales you want to use configured on your Debian system. The easiest way is to run dpkg-reconfigure locales and select those languages you want to provide (currently, stable SquirrelMail does not work with '@euro' suffixes). It's sometimes necessary to reload Apache to see the changes.
Are your clients using exotic character sets, e.g. from east-Asia? Install the 'squirrelmail-decode' package for extra character set support (Etch and up). more info
Upstream provides documentation on their website, including FAQ's, performance and security tuning. Happy SquirrelMailing!
