The Horde webmail application on our SME 7.2 server seems to set the mime-type for attachments incorrectly. For instance, office documents attached using webmail get the type text/plain, sometimes causing them to be opened in a text-editor on the recipient side.
I remember reading about similar problems on the forum some time ago, but can't find it anymore. Does anyone know what could be causing this, and how to solve it? We've just switched to PHP 5, but as far as I know the mime-type thing has been a problem on our server for quite some time...
Thanks,
