Tenon WEBmail 6.0.2

WEBmail is an easy-to-use web mail client that can be hand-tailored with your own logos, or even with your own look & feel. Like Post.Office, it supports both POP and IMAP and multiple domains.
It can even be set up with multiple mail servers for failover support. And like Post.Office, it also includes SPAM filtering and SMTP Authentication (to ensure mail server open relay protection, while giving authorized users world-wide access to the mail server).
Main features:
- Speedy, easy to use, web interface
- POP3/IMAP4 mailboxes
- Multiple mailbox support
- Modifyable layout (look and feel)
- Multiple domains from single application install
- Extensible addressbooks
- Easy multi-lingual translations
- Message Filters
- User-selectable themes.
Enhancements:
- Integrated web calendar that lets you share your calendar in a group environment to coordinate meetings. The built-in calendar security lets you endow certain users with permission to edit calendar events, while others have viewing privileges only. Users can have multiple calendars, so you can keep your personal calendar private and have public calendars for your various organizations.
