XADM: Text Attachments Modified for Internet Mail

This article has been archived. It is offered "as is" and will no longer be updated.
A small text file attachment (140 characters or fewer) containing line-feed<LF> characters, but no carriage-return line-feed combinations <CR><LF>,will be modified during outbound delivery of the Internet Mail Service. Themodification will be the extra insertion of a <CR><LF> just after theoriginal <LF> character, resulting in a <LF><CR><LF> combination at the endof each line. This may cause problems for the receiving system.
A logic error treats the text file attachment as a text/plain body partwith 7-bit encoding. Larger attachments (those greater than 140characters), are being encoded as Quoted-Printable, which correctlypreserves the <LF> character sequences.
