When a user sends a mail with an HTML file as attachment, the HTML  
file can't be displayed correctly on mail readers program, due to lack  
of charset information in the MIME Part.

/!\ note /!\ The attached file is a patch for horde-webmail 1.2.4. It  
has been deployed in production context since 2 months without problem

use case test :
1/ compose a new mail with horde
2/ attach a html file with a charset specified
3/ send the mail
4/ receive the mail on a mail client (thunderbird, kmail, ...)
5/ open the attachment file without save it on disk

To check the html file charset, I use the "file" commande on Linux :

$ lsb_release -a
Distributor ID: Ubuntu
Description:    Ubuntu 9.10
Release:        9.10
Codename:       karmic

$ file --mime test.html
test.html: text/html; charset=iso-8859-1
