Sending Emails

The mail module adds the ability to send mail to the BoxLang runtime

The mail ( bx-mail ) module adds the ability to send mail to the BoxLang runtime

BoxLang gives you the mail tag/construct to easily send email in text or HTML format without ceremony. Just register your mail servers in the administrators or the Application.bx and you are ready to start sending emails in a jiffy!

mail(
  subject="Your Order",
  from="[email protected]",
  to="[email protected],[email protected]",
  bcc="[email protected]"
  type="HTML"
){
  // body of the email.
  writeOutput( 'Hi there,' );
  writeOutput( 'This mail is sent to confirm that we have received your order.' );
};

Query Binding

You can even bind the mail construct with a query, and the engine will send as many emails as rows in the query for you:

var qData = userService.getNewUsers();
mail(
  subject="Welcome to FORGEBOX!",
  from="[email protected]",
  to="#qData.email#",
  query=qData
){
  writeOutput( "
    Dear #qData.name#,

    Welcome to your FORGEBOX account! Play and just do it!
  ")
};

Sending Attachments

You can also send attachments to your email destinations very easily using the mimeattach attribute or via the child mailparam() construct, which allows you to send multiple attachments or headers.

mail(
  subject="Your Order",
  from="[email protected]",
  to="[email protected],[email protected]",
  bcc="[email protected]"
  mimeattach=expandPath( "/my/path/attach.pdf" );
){
  // body of the email.
  writeOutput( 'Hi there,' );
  writeOutput( 'This mail is sent to confirm that we have received your order.' );
};

mail( subject="Attachments", to="[email protected]", from="[email protected]" ) {
	mailparam( name="Reply-To", value="[email protected]" );
	mailparam( file="c:\files\readme.txt" );
	mailparam( file="c:\files\logo.gif" );
}

Configuration

Mail server connectivity may be provided either via runtime configuration ( e.g. .boxlang.json ) or via the attributes allowed by the mail component ( see above ). An example configuration is provided below:

{
	"modules": {

		"mail": {
			// An array of mail servers
			"mailServers" : [
				{
					// The SMTP Server
					"smtp": "127.0.0.1",
					// The SMTP Port
					"port": "25",
					// The SMTP Username
					"username": "",
					// The SMTP Password
					"password": "",
					// Whether to use SSL in connection to the SMTP server
					"ssl": false,
					// Whether to use TLS in connection to the SMTP server
					"tls": false,
					// The idle timeout, in milliseconds, for connection to the mail server
					"idleTimeout": "10000",
					// The timeout, in milliseconds before giving up on attempts to connect
					"lifeTimeout": "60000"
				}
			],
			// The default encoding to use for outbound email
			"defaultEncoding" : "utf-8",
			// Whether to enable spooling of mail - when false, mail will be sent immediately
			"spoolEnable" : true,
			// The interval in fractions of seconds to process the spool
			"spoolInterval" : .50,
			// The connection timeout - defaults to null, meaning no connection timeout attempting to connect to the mail server
			"connectionTimeout" : null,
			// The following attributes are used for signing of all outbound emails
			"signMesssage" : false,
			// The signature keystore
			"signKeystore" : null,
			// The signature keystore password
			"signKeystorePassword" : null,
			// The private key alias within the keystore
			"signKeyAlias" : null,
			// The Key password within the keystore
			"signKeyPassword" : null,
			// Whether to enable mail logging
			"logEnabled" : true,
			// The severity level for logging
			"logSeverity" : "ERROR",
			// The time in minutes retain a message in the spool before the message is discarded - defaults to infinite
			"spoolTimeout" : 0,
			//  The time in minutes to try resending email before it is considered bounced - defaults to infinite
			"bounceTimeout" : 0,
			// Optional directory settings for the spool ( Defaults to BoxLang runtime home )
			"spoolDirectory" : "/usr/local/boxlang/mail/unsent",
			"bounceDirectory" : "/usr/local/mail/bounced"
