[imp] Attachment in horde IMP 4.2-RC1

[David Arndt]

  With RC1 of horde in Kolab 2.2 beta3  it is not possible to attach any file. 

  In IMP there is no possibility to attach a file, in DIMP I can choose a file, but it  is not attached. 

  Here my conf.php of IMP: 

  <?php

  The vfs is writeable for horde, the php.ini, have  

  post_max_size      = 100M  and
upload_max_size    = 50M 

  What could be the problem?
