Thank you for your replay.
I contacted the server company(xserver) and got an answer that we checked the mail log with our support, but there was no corresponding record itself. They also said usually, even if the email transmission itself fails for some reason, a record is left in the email log. So, there is a possibility that the email settings themselves on the built program are incorrect. They also said there was no situation where this service restricted SMTP.Additionally, they also mentioned that but is the host name of the server set correctly as "sv12233.xserver.jp"? Is it possible to review the settings on the mail form side once?
The below is my coding and the host name is the same of sv12233.xserver.jp.

PHPMailer Initialization
---------------------------------------------------/
$mail = new PHPMailer();
/* Add your SMTP Codes after this Line */
$mail->IsSMTP();
$mail->Host = "sv12233.xserver.jp";
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->Port = 26;
$mail->Username = "sample@junichi0220.xsrv.jp";
$mail->Password = "";
// End of SMTP
is there possibility that the file of php.ini(xserver's default file) is not good with the file of form.php?
I changed the number of port from 25 to 26 to be the same of form.php file but didn't work.
The below is a part of codes of the php.ini.

I really hope you can come up with some solutions. I am looking forward to hearing your replay and thank you for your kind support.
