EMEXIS WEBMAIL is a Webmail application based on SquirrelMail. SquirrelMail client is a complete Webmail system, but due to the concern of making it compatible with many browsers and systems, its interface has become a little impaired. EMEXIS WEBMAIL was developed with the intention of solving this deficiency. It comes with all functionality of the original Squirelmail, but with an interface that is much more friendly for the user. It mostly uses the mechanisms for handling messages from Squirrelmail.
Inbucket is an email testing service. It accepts messages for any email address and makes them available to view via a Web interface. It allows Web developers, software engineers, and system administrators to quickly see the emailed output of their applications. No per-account setup is required. Mailboxes are created on the fly as mail is received for them, and no password is required to browse the content of the mailboxes.
