Listener SMTP - edi file attachement - content type not reco

I have configured a SMTP port to receive email whith edi file attachement.

When I use the getTransportInfo service, the value of content type is multipart/mixed and not application/EDI.

I put in IS/lib/mime.types file the line “application/edi-x12 edi” and I restart the IS but it’s always the same thing, I haven’t the good value in the content type field.

What I must do to take into account the modification in the file mime.types ?

Plateforme : IS 6.5 (AIX), WmEDI 6.5.2


Best regards,
