Cool, is that feature in CVS?  I can't find it in IMP 4.1.4.  I see these 
2 settings in IMP's setup:


  - What is the maximum total size of attachments per message (in bytes)? 
Set this value to 0 for no limit. [Note, the maximum allowable size of any 
individual attachment is set via the PHP 'upload_max_filesize' parameter - 
see imp/docs/INSTALL]


  - What is the maximum total number of attachments per message? Set this 
value to 0 for no limit.


But that text indicates the per-attachment limit is set by the PHP 
'upload_max_filesize' parameter.
