=====IMP Webmail=====
IMP allows webusers to check their pop3/imap mailboxes through a web interface. IMP requires a few PHP libraries which I had not yet installed:



''**imap**''

''**gettext**''

''**libmcrypt**''



Equally important to know: IMP is a //Horde //application. The Horde application framework will be discussed separately, below.


====Imap====
To get imap running under php, I had to install:

''**imap-devel-2004-0.fdr.8.a.2.i386.rpm**''

''**imap-2004-0.fdr.8.a.2.i386.rpm**'' (you probably don't need this one if you have installed the first one)

''**imap-libs-2004-0.fdr.8.a.2.i386.rpm**''




====Gettext====
Gettext is an API for internationalizing/localizing your applications.




===Installing Gettext===

</code>


To compile Gettext you obviously need a c++ compiler.



<code c>
I will do the following:
[install: gcc-c++ 3.3.3-7.i386]
I will install/upgrade these to satisfy the dependencies:
[deps: libstdc++-devel 3.3.3-7.i386]

From this point on, installing Gettext is easy, see INSTALL file in src directory for Gettext.






====OpenSSL====
IMP also (optionally) needs OpenSSL, which had already been installed, but the ''**--with-openssl **''directive yielded some errors while running configure for PHP. So:



<code c>
I will do the following:
[install: openssl-devel 0.9.7a-35.i386]

</code>


After that, ''**--with-openssl=/usr/include/openssl**'' still complained: 



<code c>
configure: error: Cannot find OpenSSL's <evp.h>
</code>


But simply deleting the DIR was enough to solve these problems (see section PHP for all used configuration directives).






====Libmcrypt====
I have installed libmcrypt-2.5.7 by compiling the source code. Unfortunately, this resulted in a php ./configure error. The solution was found in a posting on the web:

<code c>
I started to study the config.log file more in deep.
The kick-out error was:

****
conftest.c -lmysqlclient -lmcrypt -lltdl -lresolv -lm -ldl -lnsl 1>&5
/usr/bin/ld: cannot find -lltdl
****

Then I visited
http://mcrypt.hellug.gr/mcrypt/index.html
an learned that I have to install not only libmcrypt but also
mcrypt and libmhash.
Afte installing libmcrypt it was essential to move into the "./libltdl"
folder
and type the following shell commands:
> ./configure --enable-ltdl-install
> make
> make install

After that configuring PHP with
../configure --with-apache=... --with-mysql=... --with-mcrypt=...
worked.

</code>


Also, the php documentation says this about libmcrypt: "Make sure you compile libmcrypt with the option ''**--disable-posix-threads**''//"//








==== Configuring IMP ====
Configuring IMP is not hard if you follow the standard procedures as described in the documentation. I needed something different for my system however:


=== Wishes ===
  -a single installation for all my virtual domains;
  -using a subdomain ''**webmail**'' for each of my domains, pointing directly to IMP (keep in mind that IMP runs within the Horde framework, also literally);
  -users should not have to specify their mail server (as is default in IMP);
  -users should be able to log on with their e-mail address (instead of their IMAP user name).
  -when composing a new mail message in Imp, the "from" address should be set to the user's mail address

=== Starting point ===
I have come up with a configuration that is based on the following facts:

  *the IMAP server and the web server (hence Horde and IMP) are on one system;
  *a typical e-mail address for a virtual domain on my system can be mapped to an IMAP user (which is really a Unix user on my system)



=== Actions taken ===
This is what I did for each point on the wish list:

**Ad 1.)** I have installed the horde framework outside of any specific document root (or webroot), in ''**/usr/var/shared/horde**''. Each virtual domain has in its document root a symbolic link, pointing to this directory.

I have also instructed Virtualmin to add an httpd.conf directive ''**FollowSymLinks**'' for each new virtual domain:

<code c>
<Directory ${HOME}/public_html>
Options -Indexes IncludesNOEXEC FollowSymLinks
</Directory>
</code>


This could pose a security thread. I have not been able to figure out to what extend, and what I might do about it.

**Ad 2.)** For each virtual domain, I have added a subdomain webmail (using Virtualmin). Each subdomain (i.e. the document root, called ''**public_html**'' on my system) contains a symlink to the horde source directory:

<code c>
horde -> /usr/var/shared/horde
</code>


Futhermore, I have added these httpd directives for each subdomain webmail, e.g.:

<code c>
Alias /horde/ 
/home/campinglachassagne/domains/webmail.campinglachassagne.fr/public_html/horde/

Alias /imp/ 
/home/campinglachassagne/domains/webmail.campinglachassagne.fr/public_html/horde/imp/
</code>
The "real" webroot on Apache is ''**path_to_public_html/horde/imp**''.

Using the Horde administration tools, I have specified that IMP is the authentication instrument (as it is the sole application running within Horde).

Finally, I had to make these changes to the Horde and IMP configuration files:

''**horde/config/registry.php**'':

In the array ''**applications['imp']**'':

''**'webroot' => '/imp',**''

This sets the IMP application as the root of the Horde framework.



''**horde/config/conf.php**'': ''**$conf['cookie']['path'] = '/';**''

Your session will NOT be saved, if you do not apply this setting, so you will have to log in for each page you request.



**Ad 3.)** To make life easier for our users, we specify the mail server as localhost (we can do this because IMP and the actual IMAP server are on one system):

''**/horde/imp/config/servers.php**'':

In the array ''**$servers['imap']**'':

''**'server' => 'localhost',**''



**Ad 4.)** I haven't gotten around to doing this yet. I have figured out a way to correctly fill in the domain name in the from: field, using the maildomain setting:

''**/horde/imp/config/servers.php**'':

In the array ''**$servers['imap']**'':

''**'maildomain' => strtolower(preg_replace('|^webmail\.|i', %%''%%,  $_SERVER['HTTP_HOST'])),**''

This deletes the webmail part of the HTTP_HOST. For instance, webmail.campinglachassagne.fr is converted to campinglachassagne.fr. This value is inserted in the from: field when you compose a new e-mail message.

**Ad 5.)** To display the user's mail address in the "from" field, I've added a "_prefs_hook_from_addr" hook in ''horde/config/hooks.php''. Here's the code:

<code>
// 20060918 -- Hook added by Onno Schuit (www.solin.eu). This hook depends on the _imp_hook_vinfo hook (defined
// elsewhere in this file), where  $_SESSION['solin_user_input'] must be set to whatever the user's input was 
// for the username (which is assumed to be either the local part of an email address or an entire email address).
// N.B.: $_prefs['from_addr'] must also be set to 'locked' => true in the file prefs.php.

if (!function_exists('_prefs_hook_from_addr')) {
  function _prefs_hook_from_addr($name = '') {
    
    $vdomain = getenv('HTTP_HOST');
    $vdomain = preg_replace('|^webmail\.|i', '', $vdomain);
    $vdomain = String::lower($vdomain);    
    
    //TEST
    //exit("TEST (from _prefs_hook_from_addr): \$_SESSION['solin_user_input'] =  ".$_SESSION['solin_user_input']);               
    
    if ($intPos = strrpos( $_SESSION['solin_user_input'], '@' ))  {
      # user has provided full email address, so return this at once
      return $_SESSION['solin_user_input'];
    } else {
      # user has provided local part of email address      
      return $_SESSION['solin_user_input'].'@'.$vdomain;
    }
    
    return '';
  }
}  
</code>

You also need to tell Imp to actually use this hook. You do this in ''horde/config/prefs.php'':

<code>
// user preferred email address for From: line
// If you lock this preference, you must specify a value or a hook for it in
// horde/config/hooks.php.
// Onno Schuit (www.solin.nl): if you do NOT set locked to true, then the hook will NOT be used!
$_prefs['from_addr'] = array(
    'value' => '',
    'locked' => true,
    'shared' => true,
    'type' => 'text',
    'desc' =>  _("Your From: address:"),
    'hook' => true
);
</code>



=== 20060501 – Update about configuration ===
I have installed a new version of the Horde, and Imp. I had to delete the aliases mentioned under point 2, and the real Apache webroot is now: ''**path_to_public_html/horde**''.

(No longer ''**path_to_public_html/horde/imp**'') 

I have also reversed a setting in a Horde configuration file:

''**horde/config/registry.php**'':

In the array ''**applications['imp']**'':

''**'webroot' => $this->applications['horde']['webroot'] . '/imp'**''''**,**''



To secure the installation, I have also disabled ''**horde/test.php**'' and ''**horde/imp/test.php**''. 

And I have secured the config directory:

<code c>
[root@1038 horde]# chown root.nobody config/*
[root@1038 horde]# chmod 0440 config/*
</code>



=== 20060818 – Update about 4: logging in with your email address ===
I have programmed a "hook" in the file ''**/usr/var/shared/horde/config/hooks.php**'' (line 675), so users can now log in with their "email address". The username form field in the login screen is now followed by "@yourdomain.com". This is the hook's code:

<code c>
if (!function_exists('_imp_hook_vinfo')) {
  function _imp_hook_vinfo($type = 'username')
  {
    $vdomain = getenv('HTTP_HOST');
    $vdomain = preg_replace('|^webmail\.|i', '', $vdomain);
    $vdomain = String::lower($vdomain);
            
    if ($type == 'username') {
      $arr = explode('.',$vdomain); 
      if ($intPos = strrpos( $_SESSION['imp']['user'], '@' ))  {
        $strUsername = substr($_SESSION['imp']['user'],0,$intPos);                             
        return $arr[0].'_'.$strUsername;
      } else {
        return $arr[0].'_'.$_SESSION['imp']['user'];        
      }               
    } elseif ($type == 'vdomain') {     
      return $vdomain;      
    } else {      
      return PEAR::raiseError('invalid type: ' . $type);
    }
  }
}
</code>
Notice that you can also type in a complete email address. The code will simply strip away all unnecessary text.

You also have to tell Imp to use this hook. Go to "Setup" > "Mail (Imp)" > "Custom Hooks" and tick the box for "Should we use a custom virtual users hook?".



=== Setting login tasks preferences such as maintenance ===
Go to ''**horde/imp/config/prefs.php**'' and find the ''**$prefGroups['logintasks']**'' array. The element with the key ''**members**'' is another array, containing the preferences you are looking for.

For instance, if you don't want the sent mail to be deleted monthly, look for the string ''**delete_sentmail_monthly**'' in the remainder of the file (prefs.php), and you'll find:

<code>
// purge sent-mail folders every month?
$_prefs['delete_sentmail_monthly'] = array(
    'value' => 1,
    'locked' => false,
    'shared' => false,
    'type' => 'checkbox',
    'desc' => _("Delete old sent-mail folders at beginning of month?"),
    'help' => 'prefs-delete_sentmail_monthly');
</code>

Change ''**value**'' to 0 if you don't want this to happen, and change ''**locked**'' to true if you don't want the Imp users to enable this feature for themselves.










====Forwarding email using the Forwards module====
The //Forwards// module is really a Horde module, not an Imp module. But it seems more logical to discuss email forwarding within the context of Imp.

At first, I didn't get //Forwards// to work at all. First, I had to:

  *reinstall php with --enable-ftp as a ./configure parameter (see the php sections)
  *figure out how to use the .forward file in Postfix (see the Postfix section)
Then I found out that to "Keep a copy in your local mailbox?" really means that the local user gets mentioned in the .forward file. This has the effect of "forwarding" to original destination.

However, my particular Postfix setup does not seem to allow for local users. Each and every user must be specified using either a canonical domain (i.e. non virtual domain) or a virtual (i.e. hosted) domain.

So I hacked the /horde/forwards/lib/Driver/forwards.php file. I have included the entire file below.



Right now (20060918), I have one more thing to do: allow certain users to ftp to the server. This is because Forwards uses ftp to place, update and delete the .forward file in the user's home directory. Ftp access can be granted by setting the user's shell to /bin/false. But that does not seem to be enough...

Update: yes it is enough, if you configure your firewall for the use of ftp. You should also add the shell to ''/etc/shells'' (if not already present in that file):

<code>
# cat >> /etc/shells
/bin/false
</code>

=====Horde Application Framework=====
The Horde Application Framework relies upon

  *coding standards
  *some of the PEAR API and modules
  *some of the PECL API and modules




====Pear modules====

On some systems, it may be necessary to install Pear manually, even if you have the latest php version. Issue this command to do so:

<code>
/usr/src# lynx -source http://go-pear.org/ | php
</code>

The 'pear' command is now at your service at ''**/usr/bin/pear**''.


===Log===
<code c>
[root@1038 src]# pear install /usr/src/Log-1.8.7.tgz
Optional dependencies:
'sqlite' PHP extension is recommended to utilize some features
install ok: Log 1.8.7
</code>



===Mailmime===
<code c>
[root@1038 src]# pear install /usr/src/Mail_Mime-1.2.1.tgz
install ok: Mail_Mime 1.2.1
</code>
  


===File===
<code c>
[root@1038 src]# pear install /usr/src/File-1.0.3.tgz
install ok: File 1.0.3
</code>



===Date===
<code c>
[root@1038 src]# pear install /usr/src/Date-1.4.3.tgz
install ok: Date 1.4.3
</code>





====Pecl modules====

===Fileinfo===
(Fileinfo cannot install due to a php bug)



Oops:



<code c>
[root@1038 src]# pear install /usr/src/Fileinfo-0.2.tgz
3 source files, building
running: phpize
/usr/local/bin/phpize: line 57: aclocal: command not found
`phpize' failed
</code>


According to some sources on the web, aclocal requires ''**automake**'' to be installed, so:



<code c>
I will do the following:
[install: automake 1.8.3-1.noarch]
I will install/upgrade these to satisfy the dependencies:
[deps: autoconf 2.59-3.noarch]
Is this ok [y/N]: y

Unfortunately, we run into yet another problem:



<code c>
[root@1038 src]# pear install /usr/src/Fileinfo-0.2.tgz

      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
`phpize' failed
</code>


I have reinstalled Automake from source (i.e. compiling and building), but that does not work either. Some searching on the web (http:%%//%%bugs.php.net/bug.php?id=29160&edit=2) reveals that it is really a php-bug. 



Since this module is not actually required, I'll leave this issue aside for now (until a new release of php at least).






====Installing the Horde====
I have installed the Horde source in a separate directory, outside my webroot:

''**/usr/var/shared/horde-3.0.2**''. Each individual website which needs the framework, links to this directory  (I should probably check the webserver documentation to see if this poses a security thread).



You do this by creating a symbolic link (first you rename ''**horde-x.x.x**'' to ''**horde**'')



<code c>
[root@1038 public_html]# ln -s /usr/var/shared/horde 
/home/campinglachassagne/domains/webmail.campinglachassagne.fr/public_html/horde
</code>


 which results into something like this:



<code c>
[root@1038 public_html]# pwd
/home/campinglachassagne/domains/webmail.campinglachassagne.fr/public_html
[root@1038 public_html]# ls -l *horde*
lrwxrwxrwx  1 root root 27 Jan 14 12:49 horde -> /usr/var/shared/horde
</code>







====Configuring the Horde====


The documentation is pretty straightforward, but fails to point out in any salient way that **setting the preference driver is very important**! Go to:



Administration > Setup > Horde > Preference System

The default preference driver is set to "none", so you have to specify another setting. On my system, I have used MySQL. Remember to also specify your database settings under the "database" tab.





====Installing the Horde from CVS for Whups====

Some Horde applications rely on the latest version of the Horde, which you will only find in cvs. Whups, a trouble ticketing system ("helpdesk") is one of them at the time of writing -- 20061104.

The official Horde site tells you about installing from CVS here: [[http://www.horde.org/horde/docs/?f=INSTALL.html#installing-from-cvs-or-snaphots|Installing from CVS or Snaphots]]

But the documentation does not mention that you should use the HEAD tag while installing from cvs. Here's what I did:

<code>
export CVSROOT=:pserver:cvsread@anoncvs.horde.org:/repository
cvs login
cvs co -r HEAD horde
cd horde
cvs co -r HEAD framework
</code>
(Password for repository is "horde")

To succesfully install the packages in the framework, I then had to do:

<code>
pear channel-discover pear.horde.org
</code>

- before I was able to:

<code>
cd framework
/usr/bin/php -q install-packages.php
cvs logout
</code>
