This software is an open source PHP webmail front-end with a fast AJAX interface and supports IMAP/SMTP/SSL, LDAP, folders, rich-text editor, address book, web admin panel, UTF-8, non-English languages, MySQL, cPanel, and Plesk for your existing mail server.

With WebMail Lite, users can easily access and manage their mailbox. They can check and send mail, view messages organized in threads, use Inbox, Sent, Drafts, and other folders, create new folders, set Sieve mail filters, signatures, identities, and other options. The email composer also supports drag-n-drop of images and attachments from desktop.
Furthermore, the mail viewer correctly and safely displays HTML messages by blocking JavaScript and external images. It fully supports international charsets and UTF-8, thus making it convenient for Arabic and Hebrew users by allowing them to opt for RTL (right-to-left rendering). Attachments can be downloaded with drag-n-drop, images and PDFs are previewed with thumbnails, and users can open zip and winmail.dat attachments.
The Address Book feature allows users to store contacts and groups, and import contacts from .vcf attachments and .csv files. Users can also have their own settings like time format and interface language (supports English and many others, easy to add new ones), change email account password with POPPASSD or custom plugins, set auto-responder, or automatic forwarding (with Sieve support).
Notably, WebMail Lite also offers IMAP quotas, template-based user interface with skins, and an integration API. The web-based administration panel, web installer, and cPanel/Plesk integration facilitate easy installation and configuration of WebMail Lite. Additionally, the database backend is MySQL, and it is optimized for ISPs and hosting providers.
Finally, it is important to note that the product is licensed under AGPLv3. Users can upgrade to Pro version with extended features and no AGPLv3 restrictions. All in all, WebMail Lite is a great tool for anyone who wants to access their mailbox via an intuitive interface that is feature-rich and well optimized.
