Free squirrelmail software for linux

Squirrelmail Outlook Skin Theme is based on the layout (visual interface) of the M$ Outlook 2003 over Squirrelmail (1.4.8).

travmail project is an imap webmail client which requires php but does not use the imap routines available in php.
Ive just made some rpm files available which have relocation enabled in case you want to install into a path other than the default /var/www/html using the rpm --install --prefix /var/htdocs travmail-version.rpm command line.
Please email bug reports to my email address below. If there is enough
interest Ill set up a mailing list.
Apologies for the lame name.. please suggest a better one.
Have a look at config.php and modify it for your sites settings.
As travmail uses css for styling it is very customisable (the only places where it isnt used is due to IE bugs).
There are a few different icon themes as the icon layout/format follows the naming convention of the kde icon sets so you can just untar an icon set then change the icons symlink in the styles/kde-look subdir and provided all the necessary icons are there you have a new theme. There are quite a few icon themes provided but for more visit http://www.kde-look.org
Dont use the filtering code that is in there .. I dont like it and you
probably wont either. Its in no way user friendly and not as powerful
as the procmail level of filtering Ive been used to and want.
Credit belongs with Trent Hornibrook for major features and suggestions
he has provided along the way. And thanks to purple (my gf) for
all the testing. Apologies if Ive missed anyone, email me and Ill give you your due credit.
This webmail client is inspired by all and sundry email clients.
The subdirectories reflect the open source packages travmail relies upon.
International character support is via some files from squirrelmail and
htmlarea is for the html editing .. the html to plain text is from the
phphtmlparser package.
Why another webmail client?
Complicated answer.. another project of mine is an oracle rac based (I
started it before open source databases were viable alternatives) imap/pop
data store for email and I was having trouble getting all the debug information
I needed to ensure that my implementation was correct (it still isnt .. when
it is usable Ill release it as well .. Ive been using it for a few years now
but it still has some pretty lame bugs .. the goal is for redundancy and to
only store any mime part once). For this reason and just for general
debugability (probably at the expense of quite a bit of performance) youll
find that there is a _lot_ of debug options you can turn on in
webmail_class.php
Load Testing
When load testing remember to use the script to strip out the debug code which
is not needed for production use.

Mail::Toaster is an installer for a collection of software which provides a full-featured mail server. The system is built around the qmail mail transport agent, with many additions and modifications
Main features:
- SMTP Mail Server (SMTP-AUTH, chk-user, SPF, TLS, tarpitting, RBL)
- Virtual Domain Hosting w/delegated administration
- Virtual Domain Users
- Mailing List (Ezmlm)
- AutoResponder
- Web Based E-Mail (Sqwebmail, Squirrelmail, V-Webmail)
- Web Based Domain Administration
- Mail Filtering (rbls, SpamAssassin, simscan, Qmail-Scanner)
- Virus Scanning (ClamAV, F-Prot, Uvscan)
- SMTP roaming via SMTP-AUTH, POP-AUTH, & IMAP-AUTH
- SMTP roaming via SMTP-submission (port 587)
- POP3, POP3-SSL
- IMAP, IMAP-SSL (Courier IMAP)
- CGI frontend to mail features
- Log processing and pretty graphs (via RRDutil)
- Auto-Installs of MySQL, Apache, phpMyAdmin, and more
- Centralized configuration files
- Support for clusters of qmail servers
- Builds SSL certs for Apache, Qmail, & Courier
Security - Mail::Toaster supports secure connections from the email client (via POP3, IMAP, SMTP, and webmail) to the server. If the remote (destination) email server supports it, we also encrypt the email as it travels across the public Intenet from server to server. Thus, if you happen to be using two Mail::Toasters and your email clients are configured to use SSL, you have a fully encrypted path from the email sender to the final recipient.
State of the Art Filtering - Mail::Toaster has sophisticated filtering capabilities built right in. A default installation blocks all viruses and will detect 85% of the spam. With a little bit of training, its reasonable to expect and achieve 99% spam filtering accuracy.
Flexibility - Mail::Toaster provides an extremely flexible framework to allow you to build your email system your way. This flexibility makes it easy to migrate existing systems to Mail::Toaster and also allows Mail::Toaster to work in diverse environments and OS platforms.
Support - There is a thriving and active support community available on the mailing list. The web forums are also frequented by quite a few helpful folks. If you need more support than folks are willing to provide, commercial support is available.
Enhancements:
- Primarily code quality improvements.
- Rewrites of major portions of the code using techniques described in Perl Best Practices.
- Many more tests, much better tests, and more error testing within the functions.
- A new Webmail interface.
- Its not terribly "pretty" yet, but is much more user friendly and functional.

Avelsieve or, verbosely, "SIEVE Mail Filters Plugin for Squirrelmail" is a Squirrelmail plugin for creating SIEVE scripts on a Cyrus IMAP server that runs timsieved (Tims SIEVE daemon).
Avelsieve will also be a part of Cyrusmaster, a web-based Cyrus administration tool. avelsieve project should provide the same interface of the users filters to administrators and/or helpdesk staff.
SIEVE is a mail filtering language, intended for server-side filtering of emails. See RFC 3028 and Cyrusofts page about SIEVE for more details.
The web interface provides a wizard-like interface that, in the end, creates part of a SIEVE script, a so called rule. It then assembles all the rules to form a SIEVE script.
For the sake of user-friendliness, it provides only a subset of SIEVEs functionality; the main goal was to provide a simple interface for Joe User to create server-side filters without knowing anything about the language itself.
The plugin does not provide a parser; instead, it saves PHP meta-data in the script itself, in order to continue editing and manipulation of the filters. The only thing that is supported is a script called "phpscript" on the Cyrus server. Multiple scripts are not supported yet. Ive tried to make it sane enough that it wont break a lot. Some more testing is needed - hence the beta status.
Main features:
- Simple HTML interface.
- Javascript functionality that enhances the user interaction, however there is HTML-only fallback for accessibility.
- Match messages based on email headers, size, or apply to all messages.
- Configurable number of header matches.
- Support of keeping a message, move to an existing or new folder, email redirection.
- Supports SIEVE Vacation.
- Supports SIEVE Notification action.
- Create a rule on-the-fly, while reading a message in Squirrelmail. This function will auto-detect List-Id: headers for mailing lists.
- Runs through all the rules, but supports a stop command when a rule matches.
- Change the order of rules - or delete them altogether.
- Enable / Disable rules on the fly, without deleting them.
- Make a textual description of the rule.
- Localizable.
- Automatic adaption to the capabilities of each sites SIEVE.
Enhancements:
- This release contains many important bugfixes and also adds the STARTTLS option for the ManageSieve protocol.

eXtended Account Management System is a PHP-based application suite made for managing electronic mail accounts on multiple domains in a virtual hosting environment.

Main features:
- Manage any number of domains, mailboxes and aliases
- Multiple domains can be grouped as a "site".
- If you have, for example, two domains domain1.tld and domain2.tld within site site1
- then mails to either of the two email addresses for user user (user@domain1.tld
- or user@domain2.tld) will be delivered to one mailbox.
- Autoreply (out of office) support
- Mail accounts are independent from system accounts
- Mailboxes can have quotas, which you can manage by reseller, site or user.
- Four different user-levels: Administrators, Resellers, Customers and Users
