  Hi @jchester26

  This problem should be fixed via https://github.com/aspnetzero/aspnet-zero-core/commit/a42ec83d307c35cc5e3b68c51678acc647e75b5b.

  Could you try that in your solution as well ?

  Hi @ismcagdas. OK got the page now.

  I have made the changes to module preinitialisation. However the file AbpZeroTemplateMailKitSmtpBuilder.cs does not exist at this path, I have

  src/XYZ.Core/Emailing/XYZSmtpEmailSenderConfiguration.cs

  Shall I make the changes in that file or create a new XYZMailKitSmtpBuilder.cs file?

  Hi @ismcagdas

  Yes! That worked thank you. I added the new code as an additonal public class in my existing file.

  Just one final question. When I first changed it I was using the wrong port number and an exception was thrown in the IDE and I had to continue. Is that becuase I am in debug mode? I would not want the system to stop if an exception was thown in production for a timeout if the SMTP server was unavailable.

  Yes, if you were debugging the source code, this is the expected behaviour. If you run the project using CTRL + F5 or if your project is running in the production, you will not see such a heavior.

  Hi, I know this is an old thread but I'm having this exact same problem. @ismcagdas - the link you posted returns a page not found. @jaycee26 Could you share what was the solution please?

  @johntui you need to be signed in to GitHub in order to see the page, otherwise you get 404 Page Not Found. You also need access to the AspNetZero repository on Github.

  But the following was what that commit is, and what I did to get it working;

  In aspnet-core/src/MyCompanyName.AbpZeroTemplate.Core/AbpZeroTemplateCoreModule.cs

  Add ` using MailKit.Net.Smtp; using MailKit.Security;``

  And then in the PreIntitialize() Method:

           // MailKit configuration
           Configuration.Modules.AbpMailKit().SecureSocketOption = SecureSocketOptions.Auto;
           Configuration.ReplaceService<IMailKitSmtpBuilder, AbpZeroTemplateMailKitSmtpBuilder>(DependencyLifeStyle.Transient);
  

  `

  Then in aspnet-core/src/MyCompanyName.AbpZeroTemplate.Core/Net/Emailing/AbpZeroTemplateMailKitSmtpBuilder.cs

  `using Abp.MailKit; using Abp.Net.Mail.Smtp; using MailKit.Net.Smtp;

  namespace MyCompanyName.AbpZeroTemplate.Net.Emailing { public class AbpZeroTemplateMailKitSmtpBuilder : DefaultMailKitSmtpBuilder { public AbpZeroTemplateMailKitSmtpBuilder( ISmtpEmailSenderConfiguration smtpEmailSenderConfiguration, IAbpMailKitConfiguration abpMailKitConfiguration) : base(smtpEmailSenderConfiguration, abpMailKitConfiguration) {

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

  }``

  @johntui - OK, sorry it does not work. My solution works with the template 9.3 version using sendgrid.
  The only change I made was to enable email sending in debug mode for testing. Other than that, in case it helps here are the SMTP settings I am using;

  SMTP host = smtp.sendgrid.net SMTP port = 465 Use SSL = ticked Domain name = sendgrid.net user name = apikey password = my api token from sendgrid account
