[rt-users] Force email of text/plain files to be attachments instead of inline

[Jon Tollerton]

When adding text files as attachments to emails on RT 3.8.1 the system 
seems to always include them inline instead of as attachments.  This 
causes the attachment to be difficult to access for the recipient.  I 
need to be able to send small license files to requestors with a 
particular file name.  The files themselves are about as human-readable 
as pem encoded x509 certificates, so accidental changes would be likely 
and it's confusing to the requestor.  The filename needs to be preserved 
as well.  I already have

Set(SuppressInlineTextFiles,1);

but that only seems to effect the web interface, not emails that are 
being sent out. 

Thanks,
