whastings Posted February 17, 2014 Share Posted February 17, 2014 I am still new to php, but have a fair amount of experience in other languages. Anyway I decided to start working on a CMS for my own site, and I will be using Amazons SES service to be sending emails. I have this function written to send an email to the user when they register so they can activate their account. But it would be great if I could get passed asking the SMTP server 'EHLO' and not getting a 421 timed out error code. function smtp_parse($socket, $message, $response) { global $mailSettings; if($message !== null) fputs($socket, $message . $mailSettings['newLine']); echo('Message => ' . $message . $mailSettings['newLine'] . '<br />'); $server_response = ''; while(substr($server_response, 3, 1) != ' ') { if(!($server_response = fgets($socket, 256))) return false; } echo('Response => ' . $server_response . '<br /><br />'); if($response == substr($server_response, 0, 3)) return true; else return false; } function smtp_mail($to, $to_name, $subject, $body) { global $mailSettings; if(!($socket = fsockopen($mailSettings['host'], $mailSettings['port'], $errno, $errstr, $mailSettings['timeout']))) { return false; } if(!smtp_parse($socket, null, '220')) return false; //it times out here! if(smtp_parse($socket, 'EHLO ' . $mailSettings['host'], '250')) { //Never makes it to here smtp_parse($socket, 'AUTH LOGING', '334'); smtp_parse($socket, base64_encode($mailSettings['user']), '334'); smtp_parse($socket, $mailSettings['pass'], '334'); smtp_parse($socket, 'MAIL FROM: my name <' . $mailSettings['return'] . '>', '250'); smtp_parse($socket, 'RCPT TO: ' . $to_name . ' <' . $to . '>', '250'); smtp_parse($socket, 'DATA', '354'); $headers = "MIME-Version: 1.0" . $mailSettings['newLine']; $headers .= "Connect-Type: text/html; charset=iso-8859-1"; $headers .= "To: " . $to_name . " <" . $to . ">" . $mailSettings['newLine']; $headers .= "From: my name <" . $mailSettings['return'] . ">" . $mailSettings['newLine']; $headers .= "Subject: " . $subject . $mailSettings['newLine']; $body = strtr($body, array('\r\n' . '.' => '\r\n' . '..')); smtp_parse($socket, $headers, '250'); smtp_parse($socket, $body, '250'); smtp_parse($socket, '.', '250'); smtp_parse($socket, 'QUIT', null); fclose($socket); return true; } return false; } $mailSettings = array('host' => 'email-smtp.us-east-1.amazonaws.com', 'port' => '25', 'timeout' => '2', 'identity' => 'email-smtp.amazonaws.com', 'newLine' => '\r\n', 'user' => '...', 'pass' => '...', 'return' => 'noreply@domain'); The debug response I am getting from my test email I am trying to send is Message => \r\nResponse => 220 email-smtp.amazonaws.com ESMTP SimpleEmailService-625029891Message => EHLO email-smtp.us-east-1.amazonaws.com\r\nResponse => 421 Timeout waiting for data from client.Mail sent un-succesfuly! I am probably doing something wrong, I don't know. I am trying to avoid using classes like PHPMailer, SwiftMailer, ... because I would like to learn how to do it myself. Any suggestions, pointers, and help would be great. But as I said I can't get past the EHLO to the SMTP server, as it times out afterwards.

jazzman1 Posted February 17, 2014 Share Posted February 17, 2014 Check, whether the server supports "EHLO". What happens to use "HELO" instead "EHLO". I will try to run the script on my server a bit late.

jazzman1 Posted February 17, 2014 Share Posted February 17, 2014 Yea, the script works fine to me. So, a few recommendations before to continue with this php testing script. Open up a telnet terminal from your local machine, test if the port 25 is open, and try to get the server greetings using " "EHLO" word. telnet servername.domainname.com 25 EHLO servername.domainname.com 220 srvername.domainname.com ESMTP Postfix EHLO servername.domainname.com 250-servername.domainname.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN Link to comment https://forums.phpfreaks.com/topic/286248-sending-emails-over-smtp-with-fsockopen/#findComment-1469257 Share on other sites More sharing options...

whastings Posted February 18, 2014 Author Share Posted February 18, 2014 I have no idea how about "amazon" are configured their mail servers. Alright, well thanks for at-least confirming my code does in-fact work. I will just have to keep tinkering until I figure out whats wrong. I also noticed I did not have the php_openssl.dll enabled within my php.ini file, and once I edited it I managed to get a crypto error result which I fixed which sent me back to the time-out response. I may just not have a type of authentication or module needed turned enabled/compiled in my version of php. Which would not make much sense as I am already using Amazons SES service on a open source forum software. I even compared my code against theirs and don't see anything that should effect my result. I have also uploaded the files to that same web-server to see if its just my local version of php or apache as I run nginx and php on my box. Anyway, thanks again! If you do think of anything or for me to try I would be hopelessly grateful!

kicken Posted February 18, 2014 Share Posted February 18, 2014 'newLine' => '\r\n', You have the \r\n inside single-quotes so it'll be treated literally rather than as a new-line character as intended. So when you send your message you are sending literally slash-r-slash-n and not a new line. The SMTP server is waiting for that new line before it parses the message and sends a response.

I did not realize that single and double quotes meant different things. Wow, thanks! That did the trick!

Completely missing this. When he wrote the "ELHO" works by telnet but not with php script my suggest was about mail server configuration. A good observation @kick.
