mail::ACCOUNT::send — Send a message


#include <libmail/sync.H>

#include <libmail/smtpinfo.H>

mail::ACCOUNT *mail;

class myAddMessagePull : public mail::addMessagePull {

    std::string getMessageContents();

myAddMessagePull message;

mail::smtpInfo info;



bool ok=mail->send(info, const mail::folder *saveFolder, message);

std::string errmsg=mail->getErrmsg();


This method sends a message via SMTP. The application should create a mail::ACCOUNT object, and invoke mail::ACCOUNT::login(3x) specifying a smtp:, smtps: or sendmail:url. The resulting mail::ACCOUNT's send method will be able to deliver the message.

message's getMessageContents specifies the contents of the message, which should be a valid, MIME-formatted message. getMessageContents does not have to return the entire contents of the message at once. addMessage calls getMessageContents repeatedly. getMessageContents should return the next portion of the message with each call. getMessageContents should return an empty string, after providing the entire message contents are provided. getMessageContents will be called repeatedly until it returns an empty string.


saveFolder, if not NULL, specifies that a copy of the message should also be saved in this folder. If this mail account uses the experimental SMAP protocol, a single copy of the message will be transmitted to the SMAP server, which will file the message in the folder, and send it to the designated recipients. Otherwise the message is manually saved to this folder using mail::folder::addMessage(3x), or mail::ACCOUNT::addMessage(3x).

The mail::smtpInfo object

info specifies the following parameters which are used to deliver the message:

class mail::smtpInfo {
	std::string sender;

	std::vector<std::string> recipients;

	std::map<std::string, std::string> options;
} ;

sender specifies the sender's E-mail address, in the form of "user@domain". recipients is a list of recipients' E-mail addresses. At least one recipient must be specified.

options specifies additional parameters for sending E-mail, initialized as follows:

options.insert(make_pair("novalidate-cert", "1"))

See mail::account::open(3x)) for a description of this option.

options.insert(make_pair("cram", "1"))

See mail::account::open(3x)) for a description of this option.

options.insert(make_pair("DSN", "list"))

Request a delivery status notification. list is a comma-separated list of the following keywords: "never" - do not request any receipts, not even non-delivery notices; "success" - request a delivery confirmation receipt; "fail" - request a non-delivery notice; "delay" - request a delayed delivery notice.

An error will be reported if the mail server does not implement delivery status notifications.

options.insert(make_pair("RET", "hdrs"))

Request that the delivery status notification should not include the entire original message, only its headers.

options.insert(make_pair("RET", "full"))

Request that the delivery status notifications should include the entire original message.

options.insert(make_pair("NOPIPELINING", "1"))

Do not use the PIPELININGSMTP extension even if the mail server claims to support it (workaround for buggy firewalls).

options.insert(make_pair("VERP", "1"))

Use the VERP mailing list extension. If the sender address is "sender@senddomain", then a delivery status notification for "recipient@recipientdomain" will be sent to "sender-recipient=recipientdomain@senddomain" (with certain additional details). This option is currently implemented only by the Courier mail server[1].

options.insert(make_pair("SECURITY", "STARTTLS"))

The message must be sent via TLS, and the recipient's server must present a certificate signed by a trusted, private, certificate authority. This option is currently implemented only by the Courier mail server[1].

This is not the standard STARTTLSESMTP extension. STARTTLS is always used automatically, if it's supported by the mail server.

Return Codes

This method returns true if it succeeds, or false if it fails. If the method fails, use mail::ACCOUNT::getErrmsg() to read a brief description of the error.
