Description

The SMTP_QuickSend command gives the users the ability to build and send a mail message with one command. In the event that you require greater control over your message, or the message is of a more sophisticated nature, the group of SMTP commands based on the SMTP_New command should be utilized.

hostName is the host name or IP address of the SMTP server where the message will be sent for distribution.

msgFrom is a text value containing an AddressList of one or more complete mail addresses indicating who originally sent the message. All addresses listed in the From header are visible to the recipients of the message.

msgTo contains an AddressList value of one or more complete mail addresses. The addresses identified in the msgTo header will each be sent an original copy of the message. Each recipient of the message will see any other mail addresses the message was delivered to.

subject is a text value concisely describing the topic covered in detail by the message body.

Warning: Usually, the subject of the message should not contain characters with diacritical marks (such as é, ö, etc.). However, if you want to use such “extended” characters, refer to the SMTP_SetPrefs and SMTP_Charset command descriptions.

message is a text value containing the body of the mail message. For historical reasons, the size of the message is restricted to 32 KB.

The optional sessionParam parameter sets the activation mode of the SSL protocol for the connection:

If you pass 0 or omit this parameter, the message will be sent in standard, non-secure mode. If the server proposes an update to SSL/TLS after authentication, the switchover is performed automatically (SSL/TLS operation in explicit mode).
If you pass 1, the message will be sent in SSL (synchronous mode),
If you pass 2, the message will be sent in standard mode but without supporting updating to SSL/TLS.

The optional port parameter specifies the SMTP port number to use for connection with the server. The most frequently used values are:

25 = standard non-secure STMP port (default port when parameter is omitted)
465 = SMTPS (SSL/TLS) port
587 = standard (but secure) SMTP port; pass this port for connections with a MS Exchange server (explicit mode).

The optional userName and password parameters are used to authenticate the sender with the mail server. These parameters must be passed together. Note that the most secure authentication mode supported by the server will be used (as with the default mode of the SMTP_Auth command).

Example 1

Here is an example of use of this command:

 $Host:="www.4d.com"

 $ToAddress:="adupont@4d.fr"

 $FromAddress:="jsmith@4d.com"

 $Subject:="Sales Report"

 $Message:="Can you send me the sales report for January 2009? Thanks."

 $Error:=SMTP_QuickSend($Host;$FromAddress;$ToAddress;$Subject;$Message;1)

 If($Error#0)

    ALERT("Error: SMTP_QuickSend"+Char(13)+IT_ErrorText($Error))

 End If

Example 2

Example for using the command to send a secure message through a MS Exchange server:

 $ServerName:="exchange.4d.com"

 $MsgTo:="adupont@gmail.com"

 $MsgFrom:="a.user@4d.com"

 $Subject:="Test message"

 $Message:="This is a test for sending a message in secure mode. Please do not reply."

 $Error:=SMTP_QuickSend($ServerName;$MsgFrom;$MsgTo;$Subject;$Message;0;587;"a.user";"@!password@!")
