Comments and suggestions concerning this book should be mailed to gmourani@videotron.ca © Copyright 1999-2000 Gerhard Mourani and Open Network Architecture ® 409 Linux Webmail IMP Overview Webmail IMP allows universal, web-based access to IMAP/POP3 servers and provides an address book, LDAP directory searches, full support for sending and receiving attachments, and many other features normally only found in desktop mail clients. If you have installed Apache with SSL support, clients can access and read mail through a secure manner by the way of SSL encryption. By default in this section, we are configured Webmail IMP to use database PostgreSQL and IMAP connection. The most know support for database are also available with Webmail IMP, if you prefer you can use MySQL, Oracle, Sybase, and other well know SQL, also you may chose to use POP3 instead of IMAP connection for your clients. These installation instructions assume  Commands are Unix-compatible. The source path is “/home/httpd”. Installations were tested on RedHat Linux 6.1. All steps in the installation will happen in super-user account “root”.
