mail::account::getSendFolder — Create a folder object for sending mail


#include <libmail/mail.H>

class myCallback : public mail::callback {
    void success(std::string msg);
    void fail(std::string msg);

#include <libmail/smtpinfo.H>
#include <libmail/addmessage.H>

mail::account *account;

mail::smtpInfo info;



mail::folder *folder=account->getSendFolder( const mail::smtpInfo &info,

mail::addMessage *addMessage= folder->addMessage(sendCallback);

addMessage->saveMessageContents(std::string messageText);


This function creates a special folder object: copying a message to this folder will E-mail it to the designated recipient list. The mail::account object must be an account that's capable of creating this kind of a folder (such as smtp accounts created by mail::account::open(3x)). The message may be manually added to the folder with mail::folder::addmessage(3x), or by copying a message from another folder using mail::folder::copyMessagesTo(3x).


Multiple messages may be copied to this mail::folder. Each messages is E-mail separately, to all recipients. Excersize caution to prevent an accidental request to copy an entire folder, with thousand messages, to a thousand recipients.


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 PIPELINING SMTP 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.

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.


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


mail::account::getSendFolder returns NULL if this mail::account object is not capable of sending mail. errmsg is initialized with an appropriate error message.
