[imp] attachment problem

[Pablo Javier Gonzalez Mateos]

Hi, i've just installed Horde+IMP on FreeBSD 4.9 with qmail+vpopmail+courierIMAP.

Everything worked fine but when i try to attach a file this error occurs:

 Warning: fopen(/tmp/impattC1Ubrh): failed to open stream: No such file or directory in /usr/local/www/data-dist/horde/imp/compose.php on line 329

I've put 4 MB of max size in PHP.ini.
I've tried changing this variable in imp/conf/conf.php:
$conf['compose']['use_vfs'] = false;

But nothing....

I saw that horde created this directory structure in /tmp, look:

/tmp/.horde/imp/attachments

When i send an email with an attachment, no file is created either in /tmp or /tmp/.horde/imp/attachments.

i've put -R 777 permisions to /tmp... and nothing.

I don't know what else to try, please, could you send me some help with this ?.

Thanks a lot !.

PD: 

Horde version: 2.2.4
IMP version: 3.2
PHP version 4.3.3
Apache version: 1.2.28
