[imp] Attachement size limit

[Jānis]

Hi!

i met such strange behaviuor:

whatever I do, the maximum attachemet size can be 26 214 400 bytes.

I hove no more ideas where to look for that limit:

in IMP conf there are 100 M, php.ini upload_max_filesize = 100 M,  
postfix max message size - 100 M

besides - why the check could be important in case of linked attachements?
