\r\nalternative: (relationship between HTML and PNG parts) or text part
\r\n
\r\nHowever, many MUAs compose a message using the first method, so this should=\r\n be taken care of when parsing the message.
\r\n
\r\nAdditionally, notice that the inline image has a disposition of \"attac=\r\nhment\".  Despite this being in there, the smiley should be embedd=\r\ned inline in the HTML part, not offered as an attachment.  Conversely,=\r\n the GIF image should be offered as an attachment, not displayed inline.\r\n
\r\nIf the MUA is not PGP capable, at the very least it should recognize multip=\r\nart/signed the same as multipart/mixed, and offer the application/pgp-signa=\r\nture part as an attachment.\r\n\r\n\r\n", "multipart": false, "boundary": false, "lineCount": 55, "size": 2135 }], "header": [ "Content-Type: multipart/alternative;
