Thanks Jim - I am using version 4.10 so maybe the first thing to do is get current! I have read everything I can think of and have not found any better suggestion. I get the same result when attaching other files whose formats are described in .mime.types such as audio/x-wav or audio/basic - namely they are 'recognized' by pine when attached, but the only 'content-type' statement that ever gets inserted into the headers is 'application/octet-stream'. Well, off I go... Thanks. Chuck. My web site is http://www.mhonline.net/~chuckh Parallel lines never meet, unless you bend one or both of them.
