Release Notes for IMP 5

The Horde Team is pleased to announce the first alpha release of the Internet Messaging Program (IMP) version H4 (5.0).

Description

IMP, the Internet Messaging Program, is one of the most popular webmail applications available. It allows universal, web-based access to IMAP and POP3 mail servers and provides a full range of features normally found only in desktop email clients.

Notes

This is a preview version that should not be used on production systems. This version is considered feature complete but there might still be a few bugs. You should not use this preview version over existing production data.

We encourage widespread testing and feedback via the mailing lists or our bug tracking system. Updated translations are very welcome, though some strings might still change before the final release.

Changes

The major changes compared to the IMP version H3 (4.3) are:

  • New mobile frontend
  • Much improved Ajax frontend including vertical-pane-layout
  • New IMAP library written from scratch with broad RFC support and huge performance improvements
  • More powerful search and filter functionality
  • Smart-reply feature
  • Localized special folders
  • Better display of HTML messages
  • HTML signatures
  • Draft auto-saving
  • Support for custom IMAP flags
  • Reduced memory usage
