I think you should look in the PEAR configuration.
Hi.
I'm not sure how the mechanism which determines whether an attachment
is shown in-line or as a link can be configured.
My users exchange large ".dwg" (Autocad) files that are displayed inline
and causes the browser to hang. I have no problem with most other
attachments (.doc .pdf etc) that are displayed as links. I want all
atachments to show up as links.
Is this a global mime configuration related to the (linux) server,
apache, php or roundmail
regards,
