Nodes contain e-mail field in CCK and are listed in Views.
When I choose a few nodes, email with attachement is send only to first node in list. Other are without attachements.
Views Bulk Operations (VBO) 6.x-1.9
Mime Mail 6.x-1.x-dev (2009-cz.-08) + Rules patch ( http://drupal.org/node/501722 )
Before I applay a path I used a PHP code in Rules with Mimemail function:
function mimemail($sender, $recipient, $subject, $body, $plaintext = NULL, $headers=array(), $text = NULL, $attachments = array(), $mailkey = '')
and it also sent attachement only to the first node in list.
