Description
This class represents an e-mail message for use with the SMTPClientSession and POPClientSession classes.
MailMessage supports both old-style plain text messages, as well as MIME multipart mail messages with attachments.
For multi-part messages, the following content transfer encodings are supported: 7bit, 8bit, quoted-printable and base64.

Constructors
MailMessage
MailMessage(
PartStoreFactory * pStoreFactory = 0
);
Creates an empty MailMessage.
If pStoreFactory is not null, message attachments will be handled by the object created by the factory. Most common reason is to temporarily save attachments to the file system in order to avoid potential memory exhaustion when attachment files are very large.
Destructor
~MailMessage
virtual ~MailMessage();
Destroys the MailMessage.
Member Functions
addAttachment
void addAttachment(
const std::string & name,
PartSource * pSource,
ContentTransferEncoding encoding = ENCODING_BASE64
);
Adds an attachment to the mail message by calling addPart(name, pSource, CONTENT_ATTACHMENT, encoding);
The part name, and the filename specified in the part source must not contain any non-ASCII characters. To include non-ASCII characters in the part name or filename, use RFC 2047 word encoding (see encodeWord()).
addContent
void addContent(
PartSource * pSource,
ContentTransferEncoding encoding = ENCODING_QUOTED_PRINTABLE
);
Adds a part to the mail message by calling addPart("", pSource, CONTENT_INLINE, encoding);
The part name, and the filename specified in the part source must not contain any non-ASCII characters. To include non-ASCII characters in the part name or filename, use RFC 2047 word encoding (see encodeWord()).
addPart
void addPart(
const std::string & name,
PartSource * pSource,
ContentDisposition disposition,
ContentTransferEncoding encoding
);
Adds a part/attachment to the mail message.
The MailMessage takes ownership of the PartSource and deletes it when it is no longer needed.
The MailMessage will be converted to a multipart message if it is not already one.
The part name, and the filename specified in the part source must not contain any non-ASCII characters. To include non-ASCII characters in the part name or filename, use RFC 2047 word encoding (see encodeWord()).
addRecipient
void addRecipient(
const MailRecipient & recipient
);
Adds a recipient for the message.
createPartStore
PartSource * createPartStore(
const std::string & content,
const std::string & mediaType,
const std::string & filename = ""
);
Returns either default StringPartSource part store or, if the part store factory was provided during construction, the one created by PartStoreFactory. Returned part store is allocated on the heap; it is caller's responsibility to delete it after use. Typical use is handler passing it back to MailMessage, which takes care of the cleanup.
encodeWord
static std::string encodeWord(
const std::string & text,
const std::string & charset = "UTF-8"
);
If the given string contains non-ASCII characters, encodes the given string using RFC 2047 "Q" word encoding.
The given text must already be encoded in the character set given in charset (default is UTF-8).
Returns the encoded string, or the original string if it consists only of ASCII characters.
getContent
const std::string & getContent() const;
Returns the content of the mail message.
A content will only be returned for single-part messages. The content of multi-part mail messages will be reported through the registered PartHandler.
getContentType
const std::string & getContentType() const;
Returns the content type for the message.
getDate
Poco::Timestamp getDate() const;
Returns the value of the Date header.
getSender
const std::string & getSender() const;
Returns the sender of the message (taken from the From header field).
getSubject
const std::string & getSubject() const;
Returns the subject of the message.
isMultipart
bool isMultipart() const;
Returns true iff the message is a multipart message.
parts
const PartVec & parts() const;
Returns const reference to the vector containing part stores.
read
void read(
std::istream & istr,
PartHandler & handler
);
Reads the MailMessage from the given input stream.
If the message has multiple parts, the parts are reported to the PartHandler. If the message is not a multi-part message, the content is stored in a string available by calling getContent().
read
void read(
std::istream & istr
);
Reads the MailMessage from the given input stream.
The raw message (including all MIME parts) is stored in a string and available by calling getContent().
See also: Poco::Net::MessageHeader::read()
recipients
const Recipients & recipients() const;
Returns the recipients of the message.
setContent
void setContent(
const std::string & content,
ContentTransferEncoding encoding = ENCODING_QUOTED_PRINTABLE
);
Sets the content of the mail message.
If the content transfer encoding is ENCODING_7BIT or ENCODING_8BIT, the content string must be formatted according to the rules of an internet email message.
The message will be sent as a single-part message.
Note that single CR or LF characters as line delimiters must not be used. Content lines always should be terminated with a proper CRLF sequence.
setContentType
void setContentType(
const std::string & mediaType
);
Sets the content type for the message.
setContentType
void setContentType(
const MediaType & mediaType
);
Sets the content type for the message.
setDate
void setDate(
const Poco::Timestamp & dateTime
);
Sets the Date header to the given date/time value.
setRecipients
void setRecipients(
const Recipients & recipient
);
Clears existing and sets new recipient list for the message.
setSender
void setSender(
const std::string & sender
);
Sets the sender of the message (which ends up in the From header field).
The sender must either be a valid email address, or a real name followed by an email address enclosed in < and >.
The sender must not contain any non-ASCII characters. To include non-ASCII characters in the sender, use RFC 2047 word encoding (see encodeWord()).
setSubject
void setSubject(
const std::string & subject
);
Sets the subject of the message.
The subject must not contain any non-ASCII characters. To include non-ASCII characters in the subject, use RFC 2047 word encoding (see encodeWord()).
write
void write(
std::ostream & ostr
) const;
Writes the mail message to the given output stream.

appendRecipient
static void appendRecipient(
const MailRecipient & recipient,
std::string & str
);
contentTransferEncodingToString
static const std::string & contentTransferEncodingToString(
ContentTransferEncoding encoding
);

void handlePart(
std::istream & istr,
const MessageHeader & header,
PartHandler & handler
);
lineLength
static int lineLength(
const std::string & str
);

std::istream & istr,
const MessageHeader & header,
PartHandler & handler
);

void setRecipientHeaders(
MessageHeader & headers
) const;

static void writeEncoded(
std::istream & istr,
std::ostream & ostr,

) const;
