39 * PHP RFC821 SMTP client
41 * Implements all the RFC 821 SMTP commands except TURN which will always return a not implemented error.
42 * SMTP also provides some utility methods for sending mail to an SMTP server.
52 public $SMTP_PORT = 25;
55 * SMTP reply line ending (don't change)
58 public $CRLF = "\r\n";
61 * Debug output level; 0 for no output
67 * Sets the function/method to use for debugging output.
68 * Right now we only honor 'echo' or 'error_log'
71 public $Debugoutput = 'echo';
74 * Sets VERP use on/off (default is off)
77 public $do_verp = false;
80 * Sets the SMTP timeout value for reads, in seconds
86 * Sets the SMTP timelimit value for reads, in seconds
89 public $Timelimit = 30;
92 * Sets the SMTP PHPMailer Version number
95 public $Version = '5.2.6';
