[horde] Attachment download problems

[=?us-ascii?Q?Alejandro Flores L=F3pez?=]

Hi there guys.
Im new to horde, its really cool!
im having some troubles, when we check the webmail and we have attachments, if the attach is >5mbs i cannot recover the file, in fact i make click on download and appear something happend and thats all, i make again click on download.. again the same, however with attachments <3 mbs it works cool. 
My theory was the attachment size on php.ini or php.init or /etc/httpd/conf.d/php.conf i have checked all that files and the values looks good, i have cheked my hard disk space for tmp , no problem.
Does exist something iam missing to fix this trouble?

Thanks in advance

Im using Linux, plesk, horde ver 2.2.3




Best regards.
