IMP - The Horde Project

Community » Applications » IMP

IMP is the Internet Messaging Program. It is written in PHP and provides webmail access to IMAP and POP3 accounts. It uses the best-of-class Horde/Imap_Client library to provide fast, robust connections to the remote IMAP/POP3 server. IMP provides multiple view types to support all possible browsers (desktop vs. mobile vs. tablet vs. text only).

IMP passes both the MIME Torture Test and the newer E-Mail Acid Test, ensuring that messages are displayed as intended by the original sender.
