They hate top-posting here....

Login to the normal horde (non dimp, use imp instead)
You must be an administrator
Choose Administration>Setup>Horde>Logging
Set it to something like Debug and choose a log file path (eg:   
/tmp/horde-debug.log)
Try to send a file and see what it says.

Messages like:

HORDE [debug] [horde] Max memory usage: 9115640 bytes [pid 4365 on  
line 340 of "/opt/wwwroot/html/horde/lib/Horde/Registry.php"

Are totally fine, it's just telling you how much memory it used to  
accomplish a certain task.
