I am getting the error as smtp exception

Unable to read data from the transport connection: net_io_connectionclosed.

What I have tried:

C#

client.Host = "smtp.bizmail.yahoo.com";
client.Port = 465;
client.EnableSsl = true;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = true;
client.Credentials = new System.Net.NetworkCredential("xxx@yahoo.com", "xxxxxxx");

Try port 587 instead of 465.

Please confirm, if u r enable to send mail to a single user.

Try client.UseDefaultCredentials = false;

Ultimately you shouldn't be sending email through yahoo, your ISP or webhost will provide an SMTP server for you to use.

I suspect your Port is incorrect. Try changing it to 587 instead.

Are you able to send mail to a single user, using shared configurations?
