ISPConfig SMTP configuration

Hi ,
I have installed ispconfig successfully. But when i am testing with php library PHPmailer for sending email from PHP.
I have tried with smtp port 25 and 26.

I got this error message : SMTP Error: Could not connect to SMTP host.
Please help me to solve this.

Below is my php code example.

$smtp_from = '[email protected]';
$smtp_host = 'mail.tobiku.com';
$smtp_username = '[email protected]';
$smtp_password = 'xxxxxx';
$smtp_port = 25;

//send email
$PHPMailer = new PHPMailer();

$PHPMailer->IsHTML(true);
$PHPMailer->From = $smtp_from;
$PHPMailer->FromName = 'Tobiku';
$PHPMailer->Sender = $smtp_from;
$PHPMailer->AddReplyTo($smtp_from, 'Tobiku');

$PHPMailer->Host = $smtp_host;
$PHPMailer->Username = $smtp_username;
$PHPMailer->Password = $smtp_password;
$PHPMailer->Port = $smtp_port;

$PHPMailer->IsSMTP();
$PHPMailer->SMTPSecure = 'tls';
$PHPMailer->SMTPAuth = true;


$PHPMailer->Subject = 'Sbjct Email';

$PHPMailer->IsHTML(true);

$msg_html = 'Test body';

$PHPMailer->MsgHTML($msg_html);


$PHPMailer->AddAddress('[email protected]', "Username");
$PHPMailer->Send();

 

Hi Till,

Hi ,

I got this by running command line : openssl s_client -connect mail.tobiku.com:587 -starttls smtp


Start Time: 1708161161
Timeout : 7200 (sec)
Verify return code: 18 (self signed certificate)
Extended master secret: no
Max Early Data: 0


This error : Verify return code: 18 (self signed certificate) ,
how to bypass this self signed certificate ?

 

Hi Till,
Is there any tutorial of installatiion free ssl auto sign for ispconfig?

 

I am looking for a good HOWTO on how to effectively rollout an email server using the howtoforge tutorial "The Perfect Server - Debian Lenny with ISPConfig 3" as a baseline installation starting point.

I have searched up and down howtoforge and other linux help forums to no avail ( I see tutorials for ISP Config 2, but it clearly states it will not work with ISPConfig 3 ), but I have started to favor this community for the fast responses and willingness to help =) so I will ask here first.

Anyone have any experience and offer any insight on how to start a email server, configuration files worth looking at, external links to tutorials elsewhere, books, or anything I can learn about to start this service?

Any help is, as always, very appreciated
