Example
echo send_mail (' fuweng#im286.com ', ' letter title ', ' sending content ');

function Send_mail ($to, $subject = ' No subject ', $body) {
$loc _host = "im286"; The name of the sending computer, can be arbitrarily
$SMTP _ACC = "fuweng#im286.com"; SMTP authenticated user name, similar to fuweng@im286.com, or Fuweng
$SMTP _pass= "Password"; SMTP authentication password, generally equivalent to POP3 password
$SMTP _host= "smtp.im286.com"; SMTP server address, similar to smtp.tom.com
$from = "fuweng#im286.com"; e-mail address of sender, your email address
$headers = "Content-type:text/plain; Charset=\ "gb2312\" \r\ncontent-transfer-encoding:base64 ";
$lb = "\ r \ n"; LineBreak

$HDR = Explode ($lb, $headers); Parsed HDR
if ($body) {$bdy = Preg_replace ("/^\./", ".", Explode ($lb, $body));} The body after parsing

$SMTP = Array (
1, EHLO, looking forward to return 220 or 250
Array ("EHLO". $loc _host. $lb, "220,250", "HELO Error:"),
2, send Auth Login, look forward to return 334
Array ("AUTH LOGIN". $lb, "334", "AUTH Error:"),
3, send the BASE64 encoded user name, expect to return 334
Array (Base64_encode ($smtp _acc). $lb, "334", "Authentification Error:"),
4, send the password encoded by BASE64, expect to return 235
Array (Base64_encode ($smtp _pass). $lb, "235", "Authentification Error:"));
5. Send mail from, expecting to return 250
$SMTP [] = Array ("MAIL from: <" $from. " > ". $lb," "," "MAIL from Error:");
6, send rcpt to. Expect to return 250
$SMTP [] = Array ("RCPT to: <" $to. " > ". $lb," "," RCPT to Error: ");
7, send data, look forward to return 354
$SMTP [] = Array ("Data". $LB, "354", "Data error:");
8.0. Send from
$SMTP [] = Array ("From:". $from. $lb, "", "");
8.2. Send To
$SMTP [] = Array ("To:". $to. $lb, "", "");
8.1, send the title
$SMTP [] = Array ("Subject:". $subject. $lb, "", "");
8.3. Send Other header content
foreach ($hdr as $h) {$SMTP [] = Array ($h. $lb, "", "");}
8.4, send a blank line, end header send
$SMTP [] = Array ($lb, "", "");
8.5. Sending the subject of the letter
if ($bdy) {foreach ($bdy as $b) {$SMTP [] = Array (Base64_encode ($b. $lb). $lb, "", "");}}
9, send "." Indicates the end of the letter, expecting to return 250
$SMTP [] = Array (".". $LB, "+", "DATA (end) Error:");
10, send quit, quit, look forward to return 221
$SMTP [] = Array ("Quit". $lb, "221", "Quit Error:");

Open the SMTP server port
$fp = @fsockopen ($smtp _host, 25);
if (! $fp) echo "Error: cannot conect to". $smtp _host. "
";
while ($result = @fgets ($fp, 1024x768)) {if (substr ($result, 3,1) = = "") {Break;}}

$result _str= "";
Sending commands/Data in an SMTP array
foreach ($smtp as $req) {
Send Message
@fputs ($fp, $req [0]);
If you need to receive server return information,
if ($req [1]) {
Receive information
while ($result = @fgets ($fp, 1024)) {
if (substr ($result, 3,1) = = "") {break;}
};
if (!strstr ($req [1],substr ($result, 0, 3))) {
$result _str.= $req [2]. $result. "
";
}
}
}
Close connection
@fclose ($FP);
return $result _str;
}
?>
