[imp] Session expired when attaching a file

[SSRI]

Hi,

We have a problem when attaching a file larger than php's
upload_max_filesize. After uploading the file, the session expires.

Horde

$conf['vfs']['type'] = 'None';

Imp

$conf['compose']['attach_size_limit'] = 41943040;
$conf['compose']['link_attachments'] = false;
$conf['compose']['use_vfs'] = false;

php

post_max_size = 60M
upload_max_filesize = 40M

PHP Warning:  POST Content-Length of 81326886 bytes exceeds the limit
of 41943040 bytes in Unknown on line 0, referer:
