I've created a custom "send an email" button with a URL hack as follow:
/_ui/core/email/author/EmailAuthor?p3_lkid={!RMA__c.Id}&retURL={!RMA__c.Link}&p2_lkid={!RMA__c.ContactID__c}&template_id=00X50000001oz0c
.
Now - I would like to add all the attachments on the record to the opened letter, is it possible via URL hack? javascript? or maybe even apex class (I dont want to use single email)?
example to clarify: User clicks the custom send an email on the contact record and the EmailAuthor screen opens, now he wants all the attachments on that contact record automatically be added to this email.
