Beonex Communicator is Mozilla polished for end users. It contains Navigator, Mailnews, Composer, and ChatZilla. Navigator has support for key web standards and a convenient interface. For example, it eases searching the Internet, similar to Apple's Sherlock on Macintosh. The Bookmark Manager can deal with huge collections of bookmarks and allows you to overview and sort them while you are surfing. If you want, you can track the latest headlines or webcams using the Sidebar. The Mailnews client supports multiple IMAP, POP3 and/or news accounts for each user, so you can download and manage all your email from various accounts in one place and store them on your computer or the server. Beonex puts a strong emphasis on security, privacy, and netiquette, to protect the private or confidential information on your computer and to encourage fairness.

It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
Enigmail is an extension for the mail client of Mozilla, Netscape 7.x, and Mozilla Thunderbird that allows users to access the authentication and encryption features provided by the popular GnuPG software. It can encrypt/sign mail when sending, decrypt/authenticate received mail, and import/export public keys. It supports both the inline PGP format and the PGP/MIME format, which can be used to encrypt attachments, and is cross-platform, although binaries are supplied only for a limited number of platforms. Enigmail uses inter-process communication to execute GPG to carry out encryption/authentication.
The WaMCom project tries to create versions of Mozilla that are more stable and correct than official Mozilla milestones. In order to achieve that, stable Mozilla releases are extended with backported correctness fixes from the ongoing Mozilla development. In addition, it contains some selected enhancements not yet available in the official Mozilla project, mostly in the areas of security and cryptography. Examples are APOP authentication for POP3 mail, SMTP/SSL, and support for crypto.signText().

It allows site administrators to update amavisd-new values, spam-assassin values, greylisting, domains checks, and sender verification. It can also provide datacenter admins with a central point of access, by having APC Masterswitch configuration and access, hosting access requests, and PPTP access and statistics views.
Zimbra is a next-generation enterprise messaging and collaboration system. It features an Ajax Web client with conversation views, fast email search, Web service mash-ups, shared calendars, document authoring, and IM. The server also syncs to MS Outlook (via MAPI), the Apple desktop (via iSync, iCal, and CalDAV), POP/IMAP clients, and mobile devices (BlackBerry, smart phones, HTML Web browsers). A version of the Web client, Zimbra Desktop, also works offline with any POP/IMAP server. Administrators can control live backup/restores of individual or groups of mailboxes, hierarchical storage (HSM) and clustering, LDAP directory configuration, Web services integration with existing enterprise applications, and integrated anti-spam and anti-virus.
