[SOVLED] Test Email Issue in Thold

[aaron0801]

Hi all,

When I send a test mail, I will receive the below error message.

Sending Message...

ERROR: SMTP Host does not appear to support authenication: 503 5.5.2 Send hello first.
SMTP Host does not appear to support authenication: 503 5.5.2 Send hello first.

I think Thold only supports HELO authentication but not EHLO which my mail system authentication. If so, what should I do to make Thold support EHLO?

My environment:
Windows Server 2003
Cacti 0.8.7b
PA 2.1
PHP 5.2.6

Thank you

I could easily add the configuration in to do both, but I believe according to the RFC (its been a while since I was working on the Squirrelmail project), that the HELO command is mandatory. The EHLO command is used to show extended services, but the server must be able to fall back to the HELO command if no EHLO command is given.

Thank you for your reply

If as you said, how can I fix my issue?

BTW, my mail system is Exchange 2003

If you are using Exchange 2003:

1. Remove SMTP authentication, as this is not necessary
2. Ensure that your Cacti box is allowed to relay through the Virtual SMTP Server on Exchange
3. If you make any changes to the Virtual SMTP Server, you need to stop and restart it.

Hope this helps.

Hi mcutting

Thank you for your relay.

I'm not our company Email system administrator, so I can't configure it....But I can do some test to give you some information.

I telnet my-email-server port 25 from cacti box, and enter HELO sucessfully as below

220 ****** Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 rea
dy at Wed, 4 Feb 2009 19:13:10 -0700
HELO
250 ****** Hello [***.***.***.***]

It seems that my email server supports HELO authentication, and I can also send mail by SMTP command line without EHLO authentication from cacti box sucessfully.

However, why I can't send mail from Cacti?

Thank you

Hello i have same error today. But i did something.

First use telnet command to mail sever which you entered in settings screen

xxx@xxx:~$ telnet smtp.xxx.com 25
Trying xxx.xxx.xxx.xxx...
Connected to smtp.xxx.com.
Escape character is '^]'.
220 STT1EXF09.TTHMC.LOCAL xxx Mail Server Thu, 5 Mar 2009 15:08:47 +0200

[b]helo xxx.com[/b]

250 STT1EXF09.TTHMC.LOCAL Hello [xx.xx.xx.xx]

ehlo

Afte these edit <cacti_path>/plugins/settings/include/mailer.php file and find Start SMTP conversation line and add lines with rows that written bold. You şhould add "fgets($smtp_sock,4096);" as many as number of lines after insert ehlo command in telnet command.

/* Start SMTP conversation */
fputs($smtp_sock, "HELO " . $this->Config["Hostname"] . "\r\n");

$smtp_response = fgets($smtp_sock, 4096);
if (substr($smtp_response,0,3) != "250") {
$this->Error = "Error returned by SMTP host: " . $smtp_response;
fclose($smtp_sock);
return false;
}



fputs($smtp_sock, "EHLO\r\n");
fgets($smtp_sock,4096);
fgets($smtp_sock,4096);
fgets($smtp_sock,4096);
fgets($smtp_sock,4096);
fgets($smtp_sock,4096);



it worked for me. I hop it solved your problem.

Thank you

Just looked at this again. Judging by the output of the telnet command, and the evidence of several ******** where the name of the host should be, it may well be that you are running a PIX with MailGuard on it ?

[cigamit]

Again... I believe HELO is mandatory by the SMTP RFC. If your server does not properly support it, then A. you should contact the vendor to fix it or B you should contact your system administrator.

I may add a patch in (the one above certainly is not ideal) but more likely I will add some more debug messages to the class to show exactly what the issue is.

Hi all,

I'm sorry for reply late.

I left the SMTP Username and password blank, then my issue was fixed....


Thanks all of you

Ok, no patch required PEBKAC!
