Email Configuration #5328 | Support Center

jehadk created 6 years ago

We Have problem in sending the email Version# AspNetZeroCore v5.3.0

An error occurred while attempting to establish an SSL or TLS connection.

The SSL certificate presented by the server is not trusted by the system for one or more of the following reasons:

The server is using a self-signed certificate which cannot be verified.
The local system is missing a Root or Intermediate certificate needed to verify the server's certificate.
The certificate presented by the server is expired or invalid.

See <a class="postlink" href="https://github.com/jstedfast/MailKit/blob/master/FAQ.md#InvalidSslCertificate">https://github.com/jstedfast/MailKit/bl ... ertificate</a> for possible solutions.

Error MailKit.Security.AuthenticationException: 'AuthenticationInvalidCredentials: 5.7.3

Authentication unsuccessful' /// Define new class public class MyMailKitSmtpBuilder : DefaultMailKitSmtpBuilder { public MyMailKitSmtpBuilder(ISmtpEmailSenderConfiguration smtpEmailSenderConfiguration) : base(smtpEmailSenderConfiguration) { }

protected override void ConfigureClient(SmtpClient client) { client.ServerCertificateValidationCallback = (sender, certificate, chain, errors) => true; base.ConfigureClient(client); } }

I implement in the PreInitialize below code /////////PreInitialize// Configuration.ReplaceService(typeof(IEmailSenderConfiguration), () => { Configuration.IocManager.IocContainer.Register( Component.For<IEmailSenderConfiguration, ISmtpEmailSenderConfiguration>() .ImplementedBy<BarznWebSmtpEmailSenderConfiguration>() .LifestyleTransient() ); }); Configuration.ReplaceService<IMailKitSmtpBuilder, MyMailKitSmtpBuilder>(DependencyLifeStyle.Transient); //////////////////////////////////////////////////////////////

Hi @jehadk,

Please override ConfigureClient as follow:

protected override void ConfigureClient(SmtpClient client)
{
    client.Connect(
        _smtpEmailSenderConfiguration.Host,
        _smtpEmailSenderConfiguration.Port,
        SecureSocketOptions.Auto
    );

    if (_smtpEmailSenderConfiguration.UseDefaultCredentials)
    {
        return;
    }

    client.Authenticate(
        _smtpEmailSenderConfiguration.UserName,
        _smtpEmailSenderConfiguration.Password
    );
}

As mentioned in [https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.MailKit/DefaultMailKitSmtpBuilder.cs#L35])

Configuration.ReplaceService<IMailKitSmtpBuilder, MyMailKitSmtpBuilder>(DependencyLifeStyle.Transient);

Just call ReplaceService to replace the built-in service.

The final problem here is : Authentication unsuccessful Be sure that you are using the correct credentials.

Yesterday I received a project for jehadk.

client.Connect( _smtpEmailSenderConfiguration.Host, _smtpEmailSenderConfiguration.Port, MailKit.Security.SecureSocketOptions.Auto ); This will resolve the certificate issue encountered.

But the current prompt: "AuthenticationInvalidCredentials: 5.7.3 authentication failed"

Thanks @maliming :). I think @jehadk should investigate "authentication failed" error. This doesn't seem like a problem related to AspNet Zero.

You can do something like this

MailMessage mail = new MailMessage { Subject = "Subject", Body = "Message", IsBodyHtml = true }; mail.Attachments.Add(new Attachment(stream, "invoice.pdf")); await this._emailSender.SendAsync(mail);

Refer to <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/2442">https://github.com/aspnetboilerplate/as ... ssues/2442</a>
