Enabling IMP

H-Sphere 2.1 comes with two webmail packages you can select from: IMP and SqWebmail. To set IMP instead of SqWebmail, follow these steps:

1. Log in as root
2. Open the file hsphere.properties:
   vi ~cpanel/shiva/psoft_config/hsphere.properties
3. Add or uncomment the following line:
   WEB_MAIL = IMP
4. Make sure the file has the following line:
   IMP_HOST = HSPHERE_WebWhereIMPisInstalled_LSERVER_ID
   where HSPHERE_WebWhereIMPisInstalled_LSERVER_ID can be obtained from E.Manager -> LServers.
5. Restart H-Sphere.

To switch back to SqWebMail repeat 1-2 steps above. Then comment out the "WEB_MAIL = IMP" string and restart H-Sphere CP.
After this H-Sphere will start using the SqWebMail instead of IMP.

Note: You can download custom IMP themes at the developers' site http://www.horde.org/themes/

Setting SMTP server for IMP

IMP configuration is written in the /hsphere/shared/apache/htdocs/horde/config/horde.php file.

IMP is configured in such way that it uses local sendmail as SMTP server by default. To configure IMP to use external SMTP server, modify horde.php in the following way:

1. Change the mailer type to smtp. For this, change the line:
   $conf['mailer']['type'] = 'sendmail';
   to: $conf['mailer']['type'] = 'smtp';
2. Uncomment the following line and specify the smtp server:
   $conf['mailer']['params'] = array('host' => 'smtp.example.com');
   where smtp.example.com should be a valid smtp server name.
