I have configured my imp installation (for test) witk this parameters:

$conf['compose']['use_vfs'] = true;
$conf['compose']['link_attachments'] = true;
$conf['compose']['link_attachments_notify'] = false;
$conf['compose']['link_attach_threshold'] = 4096;
$conf['compose']['link_attach_size_limit'] = 0;
$conf['compose']['link_attach_size_hard'] = 81920;
$conf['compose']['attach_size_limit'] = 0;
$conf['compose']['attach_count_limit'] = 0;

in order to get all attachment linked if the sum of them is bigger than 80K.
If I send an e-mail with an attachment smaller than 4K it is send ad  
normal attachment.
But if I send an e-mail whit an attachment bigger than 80K or with 2  
attachments (1 smaller than 4K and 1 bigger than 80K) I get an "error  
when communicating with the server" red rectangle  and in the log I  
get this error:
