send email C# using smtp server with username password authentification
- by KK
I have a piece of code that sends email.. heres the code
This is not working for me. This a remote smtp service ... and i double checked that email web access works fine .. i can login using the gui, recieve and send emails.
But when i try to do it through code .. it fails with the message ...
{System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 No AUTH command has been given.
Can anybody advise ... and also they dont have EWS exposed ie.e exchange web service ./.. this is the way to go ..
port is 25 and no SSL or TLS
