| | | * content_type - The content type for this part eg multipart/mixed |
| | | * encoding - The encoding to use, 7bit, 8bit, |
| | | * base64, or quoted-printable |
| | | * charset - Content character set |
| | | * cid - Content ID to apply |
| | | * disposition - Content disposition, inline or attachment |
| | | * dfilename - Filename parameter for content disposition |
| | | * description - Content description |
| | | * charset - Character set to use |
| | | * name_encoding - Encoding for attachment name (Content-Type) |
| | | * name_encoding - Encoding of the attachment name (Content-Type) |
| | | * By default filenames are encoded using RFC2231 |
| | | * Here you can set RFC2047 encoding (quoted-printable |
| | | * or base64) instead |
| | | * filename_encoding - Encoding for attachment filename (Content-Disposition) |
| | | * filename_encoding - Encoding of the attachment filename (Content-Disposition) |
| | | * See 'name_encoding' |
| | | * headers_charset - Charset of the headers e.g. filename, description. |
| | | * If not set, 'charset' will be used |
| | | * eol - End of line sequence. Default: "\r\n" |
| | | * body_file - Location of file with part's body (instead of $body) |
