Hi Mark,

Please can you try below options:-

1) You might need to add enableSsl="true" in the smtp/network node of web.config.

2) Check the log if email is failing

3) Try sending test email from your own controller and put it in try catch to see if email is successfully going or failing due to any specific reason.

Please let me know how it goes?

Regards, Shaishav

Thanks Shaishav

I am new to umbraco so not sure how to do all the points.

1) Could not find this in the web.config file. Where do I find these settings?

2) Yes, the email failed System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

3) Do not know how to do this.

Hi Mark,

Please can you update config with enableSsl="true" and try,

<smtp from="[email protected]">
            <network host="mail.worldsecureemail.com" port="465" userName="[email protected]" password="secret" enableSsl="true"/>
        </smtp>

Error from log suggest that your SMTP is not setup correctly causing the issue.

I updated the config file.

Health checked the connection SMTP settings are configured correctly and the service is operating as expected.

Error System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

It may be this particular email provider. Is that a possibility?

Hi Mark,

Yes it is possible. Try adding below code when project is started

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

You can refer this link:- https://our.umbraco.com/Documentation/Reference/Events/Application-Startup-v7 and add code in ApplicationStarted.

namespace MyProject.EventHandlers
{
    public class RegisterEvents : ApplicationEventHandler
    {
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            //Listen for when content is being saved
    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

        }
     }
}

We tested another email account and it worked without your new code option. It seems worldsecureemail.com blocks anyone trying to use it

Nice Mark! - lets close this issue.

Have a nice weekend.
