[imp] IMP fails to send attachments

[Bruno Negrao]

Hi all, I'm using horde 2.2 and imp 3.1 on a Redhat linux 8.0

When I try to send a file using IMP, i attach the file using the 'attach'
button. When the 'compose' page shows that the file was successfully
attached, I check the /tmp directory of the IMP server and I notice that a
file called, let's say 'impattCIIdpg' was created there - this should be the
uploaded file, right?

When I click the 'send' button, appear the following messages:
------------------------------------------------------------------
Warning: fopen("/tmp/impattCIIdpg", "rb") - No such file or directory in
/var/www/html/horde/imp/compose.php on line 319

Warning: stat failed for /tmp/impattCIIdpg (errno=2 - No such file or
directory) in /var/www/html/horde/imp/compose.php on line 320

--------------------------------------

But the file impattCIIdpg was there!!
How could I fix it?

Thank you,
