Our subscribers use a variety of mail reading software, ranging from the primitive to the sophisticated. The features of one kind of mail reader may conflict with the features of another, or with the software used to run the list. MIME attachments are a particular problem for the server software, and may cause the server to reject your post. It may make your message difficult or impossible for others to read.
