  Hello,

  You could check if you can to send email manually trough this SMTP server (enter in command promt "telnet smtp.mail.yahoo.com:995" and after that enter your credentials). You could also check at how to send email in ASP.NET.

  I think you are using wrong smtp Port.

  It should be as follows :

  Outgoing mail server (SMTP) settings:

  • SMTP server: smtp.mail.yahoo.com
  • Use SSL
  • Port: 465
  • Use authentication

  You can also check following URL :

  Hi, please set “EnableSsl” to true:

  SmtpServer.EnableSsl = true;

  Additionally, please make sure your “mailSettings”  is “web.config” is correct, please refer to the example on the following site:
