[horde] Requirement of IMP / Horde

[edwardspl at ita.org.mo]

Dear All,

Mine is FC6 System...
So, which version of php and pear is suitable for IMP ( Horde : 3.1.4 
and IMP : 4.1.4 ) ?
Due to the php can't be good for working with them as the following :

Create a test web page with "phpinfo()" function as the following result :

post_max_size = 10M
max_execution_time = 3600 ; Maximum execution time of each script, in
seconds
max_input_time = 3600 ; Maximum amount of time each script may spend
parsing request data
memory_limit = 512M ; Maximum amount of memory a script may consume
file_uploads = On
upload_max_filesize = 8M

But For IMP Display result :

1, Maximum Attachment Size: 2,097,152 bytes ( only 2MB ??? )
2, Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 1519127 bytes) in
/home/itawm/html/horde/lib/Horde/MIME/Part.php on line 1027 ( limit 8MB
??? )

Thank for your help !

Edward.
