PHPMailer version: 6.5.0
When I am trying to connect my PHPMailer script with my SMTP server I am getting this error:
SSL loaded 2021-07-07 20:57:08 Connection: opening to mail.solninjaa.com:587, timeout=300, options=array ( 'ssl' => array ( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true, ),) 2021-07-07 20:57:08 Connection failed. Error #2: stream_socket_client(): php_network_getaddresses: getaddrinfo failed: No such host is known. [C:xampphtdocsphpvendorphpmailerphpmailersrcSMTP.php line 388] 2021-07-07 20:57:08 Connection failed. Error #2: stream_socket_client(): unable to connect to mail.solninjaa.com:587 (php_network_getaddresses: getaddrinfo failed: No such host is known. ) [C:xampphtdocsphpvendorphpmailerphpmailersrcSMTP.php line 388] 2021-07-07 20:57:08 SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: No such host is known. (0) SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
The first “SSL loaded” is my script checking if it has OpenSSL enabled.
My mail server is:
mail.solninjaa.com
Note: “mail.solninjaa.com” is the IMAP and POP3 address as well.
I ran a command that would test if the mail server is actually, well, a mail server. It came back saying it wasn’t, which is very weird since I can see it running in my Webmin / Virtualmin dashboard (they are like CPanel). This could be the problem, but I doubt it. I think I might of put in the wrong port (or something like that).
I just thought that was worth mentioning.
My PHPMailer script is:
<?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; /* Composer autoload.php file includes all installed libraries. */ require '.vendorautoload.php'; $mail = new PHPMailer(TRUE); $name = $_POST['name']; $email = $_POST['email']; $message = $_POST['message']; $secretKey = "pleasedontsharethis"; $responseKey = $_POST['g-recaptcha-response']; $userIP = $_SERVER['REMOTE_ADDR']; $url = "https://www.google.com/recaptcha/api/siteverify?secret=$secretKey&response=$responseKey&remoteip=$userIP"; $response = file_get_contents($url); $response = json_decode($response); echo (extension_loaded('openssl')?'SSL loaded':'SSL not loaded')."n"; if ($response->success) { try { $mail->setFrom('otheremail@gmail.com', 'SolninjaA'); $mail->addAddress('email@gmail.com', 'Name'); $mail->Subject = 'Testing PHPMailer 2'; $mail->msgHTML(file_get_contents('email_template.html'), __DIR__); $mail->AltBody = 'There was a malfunction with sending the HTML. Sorry.'; // $mail->isSMTP(); // $mail->Port = 587; // $mail->SMTPAuth = TRUE; // TESTING CUSTOM STMP SERVERS $mail->isSMTP(); $mail->Host = 'mail.solninjaa.com'; $mail->SMTPAuth = TRUE; $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; $mail->Username = 'noreply@solninjaa.com'; $mail->Password = 'mypassword'; $mail->Port = 587; $mail->SMTPAutoTLS = false; $mail->SMTPDebug = 3; /* Disable some SSL checks. */ $mail->SMTPOptions = array( 'ssl' => array( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true ) ); /* Finally send the mail. */ $mail->send(); } catch (Exception $e) { echo $e->errorMessage(); } catch (Exception $e) { echo $e->getMessage(); } echo "Thank You!" . " -" . "<a href='/dist' style='text-decoration:none;color:#ff0099;'> Return Home</a> we are Automatically redirecting you in 5 seconds."; header("Refresh:5; url=/dist"); } else { echo "<span style='text-decoration:none;color: red;'>Sorry, something went wrong... Invalid Captcha, please try again.</span> <a href='/dist' style='text-decoration:none;color:#ff0099;'> Return Home</a> we are Automatically redirecting you in 5 seconds."; header("Refresh:5; url=/dist"); } ?>
Note: My original script had XOAUTH2 settings commented out (// , #) but I removed those for security reasons.
Note: My script also requires Google reCaptcha, that’s why there are extra variables.
Also, if I can’t get my custom SMTP servers to work, can I make a Google Workspace account and get a XOAUTH2 token with that account? Will it show my custom email address? (noreply@solninjaa.com)

Answer
It cannot resolve mail.solninjaa.com, and neither can I.
You at least have a DNS problem.
