SMTP is rfc 821 compliant and implements all the rfc 821 SMTP commands except TURN which will always return a not implemented error. SMTP also provides some utility methods for sending mail to an SMTP server.

Methods

__construct()

__construct() : void

Initialize the class so that the data is in a known state.

Connect()

Connect(  $host,   $port,   $tval = 30) : boolean

Connect to the server specified on the port specified.

If the port is not specified use the default SMTP_PORT. If tval is specified then a connection will try and be established with the server for that number of seconds. If tval is not specified the default is 30 seconds to try on the connection.

SMTP CODE SUCCESS: 220 SMTP CODE FAILURE: 421

Parameters

	$host
	$port
	$tval

Returns

boolean

StartTLS()

StartTLS() : boolean

Initiate a TLS communication with the server.

SMTP CODE 220 Ready to start TLS SMTP CODE 501 Syntax error (no parameters allowed) SMTP CODE 454 TLS not available due to temporary reason

Returns

boolean —

success

Authenticate()

Authenticate(  $username,   $password) : boolean

Performs SMTP authentication. Must be run after running the Hello() method. Returns true if successfully authenticated.

Parameters

	$username
	$password

Returns

boolean

Connected()

Connected() : boolean

Returns true if connected to a server otherwise false

Returns

boolean

Close()

Close() : void

Closes the socket and cleans up the state of the class.

It is not considered good to use this function without first trying to use QUIT.

Data()

Data(  $msg_data) : boolean

Issues a data command and sends the msg_data to the server finializing the mail transaction. $msg_data is the message that is to be send with the headers. Each header needs to be on a single line followed by a <CRLF> with the message headers and the message body being seperated by and additional <CRLF>.

Parameters

$msg_data

Returns

boolean

Hello()

Hello(  $host = '') : boolean

Sends the HELO command to the smtp server.

This makes sure that we and the server are in the same known state.
