A customer sent an email asking us to refer to the attachment. However there did not appear to be any files attached when viewing the article in OTRS. A quick check in the database however and I found this in the article_attachment table:
content_type = application/pdf; name="3569_001.pdf"
content_id = <B2BC52F36581CB409F066C7FCE3B5F6C@Mining.local>
If I change the content_id to NULL, a link to the attachment appears as normal when viewing the ticket in OTRS. I think the problem is that when content_id is set, OTRS attempts to display the attachment inline, but this is probably not possible with a pdf document. Is there any way to alter this behaviour, for example is there a way to strip out the content_id value for pdf attachments? Thanks.
