Hi,

I am using asp.net to send email through Zoho mail. My code is as follows. However, I got an odd error "Mailbox unavailable. The server response was: Mail Account does not exist for customerservices@textbookdrive.com"

But I am absolutely sure the mailbox is created properly and I can send and receive emails manually. Please help!

Thanks,

L.Z.

System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("myaccount", "mypassword");

System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient("smtp.zoho.com", 587);

client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;

client.UseDefaultCredentials = false;

client.EnableSsl = true;

client.Credentials = credentials;

var mail = new System.Net.Mail.MailMessage(" customerservices@textbookdrive.com", "destination email");

mail.Subject = message.Subject;

mail.Body = message.Body;

await client.SendMailAsync(mail);
