Where does the MIME-type get set when adding documents?

Hi.I am adding documents using LAPI AddDocument() but they do appear to end up with the correct MIME-type automatically.I had assumed Livelink would set this property based on the file extension when it adds the document to the library. Is this not the case?All my documents appear to end up being given a MIME-type of 'Application/activemessage' (including things like .exe, .vcf, and so on).Best regards/matt.
