嗨朋友们，

我使用此代码，
Hi friends,
I just host my website and created 3 mails and configure to outlook and tested successfully incoming and outgoing mails.
now i just used my mail in coding but by coding if i sent message to my mail info@website.com from gmail it recieved message successfully but when i sent message to any gmail from my mail i cant recieve it and got error.
I used this code,
MailMessage mail = new MailMessage();
mail.To.Add("aarohi_verma@gmail.com");
mail.From = new System.Net.Mail.MailAddress("info@mywebsitename.com");
mail.Subject = "Testing from code..!";
mail.IsBodyHtml = true;
mail.Body = string.Format("<html><body><b>Dear</b>" +
" <font> Hello THis is for just testing </font><br/><br/>" +
"</body></html>");
SmtpClient smtp = new SmtpClient();
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("info@mywebsitename.com", "my mail password from control panel");
smtp.EnableSsl = true;
smtp.Send(mail);
它给出的错误如下：

推荐答案
你试试这个吗？
要么：
smtp.Host =https://smtp.gmail.com;
或
smtp.EnableSsl = false;
Did you try this?
Either make:
smtp.Host = "https://smtp.gmail.com";
OR
smtp.EnableSsl = false;
HI AAROHI
你能检查一下你的SMTP.HOST。你有单独的邮件服务器。

HI AAROHI
Could you please check your SMTP.HOST. Are you having a Mail Server separately.
