IMP is the Internet Messaging Program. It is written in [PHP] and provides WebMail access to [IMAP] and [POP3] accounts. Built on the [Horde] framework.


!! Notes

! Using multiple servers in [IMP]

AddToMe: you can log into multiple servers based on vhost: edit the array in <tt>/etc/imp3/servers.conf</tt>

! Adding a prefix based on the domain

Set <tt>$conf~['hooks']~['vinfo'] = 'imp_get_vinfo';</tt> and create a function like so (__note:__ new syntax for 3.2.2)

<verbatim>
if (!function_exists('imp_get_vinfo')) {
    function imp_get_vinfo ($type = 'username') {
        global $conf, $imp;

        $vdomain = getenv('HTTP_HOST');
        $vdomain = preg_replace('|^webmail\.|i', '', $vdomain);
        $vdomain = strtolower($vdomain);

        if ($type == 'username') {
             return strtolower($_SESSION['imp']['user'] . '@' . $vdomain);
        } elseif ($type == "vdomain") {
            return $vdomain;
        } else {
            return new PEAR_Error('invalid type: ' . $type);
        }
    }
}
</verbatim>

This syntax is for MetaNet Mail, where you log into [Cyrus] as <tt>user@domain.tld</tt>.  It will remove <tt>webmail.</tt> from the vhost you connected from, and offer <tt>@the.rest.of.it</tt> as the suffix for the login, so you only have to enter <tt>user</tt> into the webmail box.

Smarter people can make it domain by domain specific by editing the function.

! Errors using the alpha version of IMP/Horde

You need to upgrade your version of [PHP] if you're getting errors such as

<verbatim>
Fatal error: Call to undefined function: is_a() in /var/www/webmail2/horde/lib/base.php on line 35
</verbatim>

<tt>is_a()</tt> was introduced in [PHP] 4.2.0. You have to either revert to a really old version of [PEAR] (does [PEAR] even support pre-4.2.0 [PHP]?) or upgrade your [PHP] installation.
