What is IMP?
IMP, the Internet Mail Program, is one of the most popular and widely deployed open source webmail applications in the world. It allows universal, web-based access to IMAP and POP3 mail servers and provides Ajax, mobile and basic interfaces with a rich range of features normally found only in desktop email clients, including attachments, spell-check, address books, multiple mailboxes, and multiple-language support.
This software is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative.
