Hello.
Did you install AbanteCart or just upload old files? Database connection credentials in system/config.php file

Hey!

Thanks for your feedback, actually I tried everything and finally I decided to install Abantecart script within last version and rebuild my website from the beginning but,  I realized that the same problem is exist too and website does not sending verification emails to new subscribers. Also, I don't know how to upload my backed-up website to server because it has a lot of problems too. those problems i can say them after resolving the website mailer error which we have now.

AbanteCart do not send emails. Your AbanteCart use hosting server webmail or your SMTP service to send it.
So more likely the problem with mails you have is related to your server mail settings/limitation etc
