Webmail squirrelmail fails

Hi.
I've a problem about webmail.
On new sites, the url http://www.domain.tld/webmail get a download fail for login.php, and the login item don't appears.

Other sites on the same server execute it perfect.

I put suphp + suexec + this code on apache directives at options tab like the sites working fine.

Code:

<Location /webmail>
SuPHP_Engine off
AddHandler application/x-httpd-php .inc .php4 .phtml .php .php3 .php5
</Location>

<Location /squirrelmail>
SuPHP_Engine off
AddHandler application/x-httpd-php .Inc .php4 .phtml .php .php3 .php5
</Location>

Any suggestions?

AddHandler application/x-httpd-php .[B][COLOR="Red"]I[/COLOR][/B]nc .php4 .phtml .php .php3 .php5

Code:

AddHandler application/x-httpd-php .[COLOR="Red"][B]i[/B][/COLOR]nc .php4 .phtml .php .php3 .php5
