Re[2]: [PHP] Sending e-mail via socket
Hello Rene,
Can't do that since the message is personalized: I need to put in the
user name ("Hello $username") and some other data, so the BCC is not a
solution, unfortunately...

Even if the mailserver does pipelining, he'll still need to do the EHLO separately and wait for the response to see if it does. After that you can fire off everything in one go. /Per -- Per Jessen, Zürich (7.8°C) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

First, if you're using the mail() function to talk to a *local* SMTP
server, you shouldn't have a long lag at all. The local SMTP server
should queue the messages and deal with the remote connections on its
own time, withough blocking..
Second, you're doing this socket operation as though it's a static
one-sided conversation. I'm not an expert, but SMTP conversations don't
normally work this way. You issue the HELO, wait for the response, issue
other commands, wait for the response, etc. The way you're doing it, if
your SMTP conversation runs into any snags (like the RCPT TO is not
recognized), you won't know it. Your function will simply ride over the
error, because it's not listening to the SMTP server.
Again, I'm not an expert, so maybe there's something I've overlooked.

[PHP] Sending e-mail via socket
Hello everyone,
I've just subscribed to the list, and I already have a question.
what I need to do is to send mail using sockets. Actually, the
built-in Mail() function is great and I wouldn't have to search for
something else if I didn't need more than one message to be sent at a
time. Say, I have ten or a hundred of users who want to receive a
notification about new blog entries. If I use the mail() function in
the loop, it will be performed too slow since it constantly opens and
closes the door, I mean, the SMTP connection.
So I need an alternative.
And here's what I'm doing:
";
$connect = fsockopen ("smtp.yandex.ru", 25, $errno, $errstr, 30);
if ($connect) {
$out="HELO localhost\r\n";
$out.="MAIL FROM: $from\n";
$out.="RCPT TO: $to\n";
$out.="DATA\r\n";
$out.="Content-Type: text/plain; charset=utf-8\n";
$out.="To: $to\n";
$out.="Subject: $subject\n";
$out.="\n\n";
$out.=$message." \r\n";
$out.=".\r\n";
$out.="RSET\r\n";
fwrite ($connect, $out);
fclose ($connect);
} else {
die ("Error: ".$errstr." ($errno)");
}
}
socketmail ("arthae...@yandex.ru", "this is a socket mail test",
"Testing mail sending");
?>
And what I get is absolutely nothing. No errors, no warnings, no
message in the mailbox.
So three questions:
1. What's wrong with my script?
2. How to look where the error exactly is? Can't get server logs for
some reason (will talk to tech support probably).
3. How to do the same thing but with an ability to send multiple
messages without closing the connection after each message?
Thanks!
