Working SMTP with Authentication

[jrewolinski]

Thought I'd post this for anyone else needing it.

I found this here...
viewtopic.php?t=2469&highlight=smtp

But the instructions weren't very clear...so here's a better decription of what needs to be changed.

Create a new PHP file (sendmail.php) with the below contents, and save it in your main hesk directory, and also in your admin directory.

Code: Select all

<?php 

class smtp 
{ 
/* Public Variables */ 
var $smtp_port; 
var $time_out; 
var $host_name; 
var $log_file; 
var $relay_host; 
var $debug; 
var $auth; 
var $user; 
var $pass; 

/* Private Variables */ 
var $sock; 

/* Constractor */ 
function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass) 
{ 
$this->debug = FALSE; 
$this->smtp_port = $smtp_port; 
$this->relay_host = $relay_host; 
$this->time_out = 30; //is used in fsockopen() 
# 
$this->auth = $auth;//auth 
$this->user = $user; 
$this->pass = $pass; 
# 
$this->host_name = "localhost"; //is used in HELO command 
$this->log_file = ""; 

$this->sock = FALSE; 
} 

/* Main Function */ 
function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "")

$mail_from = $this->get_address($this->strip_comment($from));

Next you need to modify the 3 files that send mail.
submit_ticket.php, reply_ticket.php, and admin_reply_ticket.php

In submit_ticket.php, comment out this line..

Code: Select all

/*@mail($email,$hesklang['ticket_received'],$msg,$headers);*/

and paste the following below it.

Code: Select all

require("sendmail.php"); 
########################################## 
$smtpserver = "0.0.0.0"; //SMTP server IP address
$smtpserverport =25; //SMTP port (I had to use alternate port)
$smtpusermail = "address@domain.com"; //SMTP email address
$smtpemailto = $email; //
$smtpuser = "user"; //SMTP username for authentication
$smtppass = "passoword"; //SMTP password for authentication
$mailsubject = $hesklang['ticket_received']; //subject
$mailbody = $msg; //body
$mailtype = "TXT"; //
########################################## 
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass); 
//true 
$smtp->debug = false; //
if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)) 
{ 
//echo "send successfully!!!<br>"; 
} 
else 
{ 
//echo "send unsuccessfully!!!!<br>"; 
} 

And also comment out this line.

Code: Select all

/*@mail($email,$hesklang['new_ticket_submitted'],$msg,$headers);*/

And paste the following below it.

Code: Select all

########################################## 
$smtpserver = "0.0.0.0"; //SMTP server IP address
$smtpserverport =25; //SMTP port 
$smtpusermail = "address@domain.com"; //SMTP email
$smtpemailto = $email; //
$smtpuser = "username"; //SMTP username
$smtppass = "password"; //SMTP password
$mailsubject = $hesklang['new_ticket_submitted']; //subject
$mailbody = $msg; //body
$mailtype = "TXT"; //
########################################## 
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass); 
//true 
$smtp->debug = false; //
if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)) 
{ 
//echo "send successfully!!!<br>"; 
} 
else 
{ 
//echo "send unsuccessfully!!!!<br>"; 
} 

Next in reply_ticket.php, comment out this line..

Code: Select all

/*@mail($email,$hesklang['new_reply_ticket'],$msg,$headers);*/

And paste this below...

Code: Select all

require("sendmail.php"); 
########################################## 
$smtpserver = "0.0.0.0"; //SMTP server IP address
$smtpserverport =25; //SMTP port 
$smtpusermail = "address@domain.com"; //SMTP email
$smtpemailto = $email; //
$smtpuser = "username"; //SMTP username
$smtppass = "password"; //SMTP password
$mailsubject = $hesklang['new_reply_ticket']; //subject
$mailbody = $msg; //body
$mailtype = "TXT"; //

$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass); 
//true 
$smtp->debug = false; //
if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)) 
{ 
//echo "send successfully!!!<br>"; 
} 
else 
{ 
//echo "send unsuccessfully!!!!<br>"; 
} 

And lastly, in admin_reply_ticekt.php, comment out the following line.

Code: Select all

/*@mail($orig_email,$hesklang['new_reply_staff'],$msg,$headers);*/

And past the following below it.

Code: Select all

require("sendmail.php"); 
########################################## 
$smtpserver = "0.0.0.0"; //SMTP server IP address
$smtpserverport =25; //SMTP port 
$smtpusermail = "address@domain.com"; //SMTP email

$mailsubject = $hesklang['new_reply_staff']; //subject
$mailbody = $msg; //body
$mailtype = "TXT"; //
########################################## 
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass); 
//true 
$smtp->debug = false; //
if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)) 
{ 
//echo "send successfully!!!<br>"; 
} 
else 
{ 
//echo "send unsuccessfully!!!!<br>"; 
} 

The smtp portions of code, have a debug option as well, that will print out every step of the SMTP process, so you can make sure it works. Just don't forget to turn off the debug.

Don't forget to fill out the correct server IP address, email address, username, and password in all 4 sections.

Hope this helps, it did for me.
Thanks andrew80706 for the SMTP class code.
And thank you Klemen for the great help desk.

[Klemen]

Thanks for sharing, I'm sure a lot of users will need this and it might take a while for the official version to support it.

I moved it into the add-ons/mods forum.

[lupolo]

Wenn using this SMTP addon, i have a problem wenn using a smtp server without username and password, how must i work wenn there is ni username and password? Wenn i not filling it in it also not works.

[lupolo]

Nobody?

[fk59]

sry, but doesnt work. After running admin_reply_ticket.php a white, blank page comes up and no mail will be send.

Settings for smtpserver are correct.

Hints?

For me i worked, only get a failure becase i don't use a username and password (IP check) So I think you have done something wrong!

Still waiting for a fix with no username/password auterisation.

[jrewolinski]

Sorry, i don't check these forums very often, and I guess I don't get email notifications.
I'm not very knowledgeable about PHP, I only have minor programming expierience.

fk59, I would enable the debugging, and see what errors you get. What you're getting sounds similar to something I remember getting, but I enabled debugging, and figured it out.

lupolo, My guess, would be, if you want SMTP, withOUT Authentication, just comment out these lines, in the sendmail.php file. That's the authentication portion of code.

Code: Select all

#auth 
if($this->auth){ 
if (!$this->smtp_putcmd("AUTH LOGIN", base64_encode($this->user))) { 
return $this->smtp_error("sending HELO command"); 
} 

if (!$this->smtp_putcmd("", base64_encode($this->pass))) { 
return $this->smtp_error("sending HELO command"); 
} 
} 

Hope that helps...

[lupolo]

Worked! Many thanks!

[lupolo]

Is it also possible, to use a no-reply@ email for the email to the cusomer and use a bounce email wenn the entered mail doesent work?

It won't use the standard's:

$headers = "From: $hesk_settings[noreply_mail]\n";
$headers.= "Reply-to: $hesk_settings[noreply_mail]\n";
$headers.= "Return-Path: $hesk_settings[webmaster_mail]\n";

How does the SMTP work with the above?

[jrewolinski]

If I understand correctly... you could probably do this... Not sure if it'll work though, as I said, I'm not great with coding. There's already a built in "additional_headers" variable in the existing code, but I'm not sure about its format, so I added 2 additional header fields to the sendmail.php file.

Code: Select all

require("sendmail.php"); 
########################################## 
$smtpserver = "0.0.0.0"; //SMTP server IP address 
$smtpserverport =25; //SMTP port 
$smtpusermail = $hesk_settings[noreply_mail]; //SMTP email 
$smtpemailto = $orig_email; // 
$smtpuser = "username"; //SMTP username 
$smtppass = "password"; //SMTP password 
$mailsubject = $hesklang['new_reply_staff']; //subject 
$mailbody = $msg; //body 
$mailtype = "TXT"; // 
$mailreply = $hesk_settings[noreply_mail];     //ADD THIS LINE
$mailreturn = $hesk_settings[webmaster_mail];     //ADD THIS LINE
########################################## 
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass); 
//true 
$smtp->debug = false; // 
if($smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype, "", "", "", $mailreply, $mailreturn)) 
{ 
//echo "send successfully!!!<br>"; 
} 
else 
{ 
//echo "send unsuccessfully!!!!<br>"; 
} 

and change the following lines in your sendmail.php file.

Code: Select all

function sendmail($to, $from, $subject = "", $body = "", $mailtype, $cc = "", $bcc = "", $additional_headers = "", $hesk1 = "", $hesk2 = "")     //ADD THE LAST 2 VARIABLES

Code: Select all

$header.= "From: $from<".$from.">\r\n"; 
$header.= "Subject: ".$subject."\r\n"; 
$header.= "Reply-to: "$hesk1"\r\n";          //ADD THIS LINE
$header.= "Return-Path: "$hesk2"\r\n";       //ADD THIS LINE
$header.= $additional_headers; 
$header.= "Date: ".date("r")."\r\n"; 
$header.= "X-Mailer:By Redhat (PHP/".phpversion().")\r\n";

[lupolo]

Thank you for the reply but the hack wont work, get a white screen while submitting.

But what is $hesk1/2 ?

Nobody, who know's how to modify the script?

Hi Guys,

Just found this, which is great and I've installed it, However I'm getting an odd debug error. Hoping someone can shed some light on it for me if they've got 5 minutes.

It would appear that my SMTP server thinks something dodgy is going on and is dumping the connection.

The username it logs in with is support@pantherex.co.uk, so it should have no problem sending to John@.

I think the following will do the trick

Run this command in exchange shell:

Code: Select all

Add-AdPermission -Identity "Default Receive Connector" -User "NT AUTHORITY\Authenticated Users" -ExtendedRights ms-Exch-SMTP-Accept-Any-Sender

Remember to change Default Receive Connector to the name or your Receive Connector. This does not allow another user to spoof any internal user though according to my tests.

But still my question is open

[uziel171]

Managed to figure it . . . it was this line ( or rather this specific line in each entry :

$smtpusermail = "address@domain.com"; //SMTP email address

for some reason this was making my SMTP server think i was attempting to spoof an address.

changed it to :

$smtpusermail = ""; //SMTP email address

and it now works a treat.
