  Hi @jdavis01,

  How did you configured email settings ? Related setting is retrieved just like this

  var value = SettingManager.GetSettingValue(name);
  

  You can run this code before sending email to see if setting value is retrieved correctly or not.

  Thanks.

  Sorry for the late response.. The values are getting populated correctly because the following code retrieves all the settings...

  var output = await _tenantSettingsAppService.GetAllSettings();
  

  Here is where I get stuck. Not sure where the value is getting dropped using the original Send Test Email Button..

  $('#SendTestEmailButton').click(function () {
             _tenantSettingsService.sendTestEmail({
                  emailAddress: $('#TestEmailAddressInput').val()
              }).done(function () {
                  abp.notify.info(app.localize('TestEmailSentSuccessfully'));
              });
          });

  Hi,

  Actually, those are showing setting values but while sending an email, same setting values are retrieved again using

  var value = SettingManager.GetSettingValue(name);
  

  for each setting like from address, host, use ssl etc...

  So, that is why I asked you to check the value of

  var value = SettingManager.GetSettingValue(name);
  

  You can also copy the code of <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/blob/master/src/Abp/Net/Mail/Smtp/SmtpEmailSender.cs">https://github.com/aspnetboilerplate/as ... lSender.cs</a> into your project and use it to send email and see if it works with your settings or not. In that way, you can identify problem faster I think.

  Thanks.

  Sorry it took so long again for me to get back to this.

  I tried the sample code you recommended, and it returned null

  var value = SettingsManager.GetSettingValue(EmailSettingNames.Smtp.UserName)
  

  I finally got the email system to work however and here is how I did it..

  I had to implement ISmtpEmailSender instead of IEmailSender in the SettingsAppServiceBase.

  using System.Threading.Tasks;
  using Abp.Net.Mail;
  using wcb.ScratchPad.Configuration.Host.Dto;
  using Abp.Net.Mail.Smtp;
  
  namespace wcb.ScratchPad.Configuration
  {
      public abstract class SettingsAppServiceBase : ScratchPadAppServiceBase
      {
         // private readonly IEmailSender _emailSender;
          private readonly ISmtpEmailSender _emailSender;
  
          protected SettingsAppServiceBase(           
              ISmtpEmailSender emailSender)
          {
              _emailSender = emailSender;
          }
  
          #region Send Test Email   
          public async Task SendTestEmail(SendTestEmailInput input)
          {
              await _emailSender.SendAsync(               
                  input.EmailAddress,
                  L("TestEmail_Subject"),
                  L("TestEmail_Body")
              );
          }
  
          #endregion
      }
  }
  

  It seems that IEmailSender throws this exception no matter how many ways you populate the value.

  AbpException: Setting value for 'Abp.Net.Mail.Smtp.UserName' is null or empty!
  Abp.Net.Mail.EmailSenderConfiguration.GetNotEmptySettingValue(string name)
  

  Not sure if this is considered and acceptable solution,but it has me moving forward for now. If it is not i will raise an issue on the git repo to start tracking it.

  thanks for the support and general direction to get started debugging..

  To clean things up, and to help anyone else having this issue, I had to implement the ISmtpEmailSender in the UserMailer.cs class inside the Core project. Now the email system is working very nicely..

  Here is the change....

  /// <summary>
      /// Used to send email to users.
      /// </summary>
      public class UserEmailer : ScratchPadServiceBase, IUserEmailer, ITransientDependency
      {
          private readonly IEmailTemplateProvider _emailTemplateProvider;
          private readonly ISmtpEmailSender _emailSender;
          private readonly IRepository<Tenant> _tenantRepository;
          private readonly ICurrentUnitOfWorkProvider _unitOfWorkProvider;
  
          public UserEmailer(IEmailTemplateProvider emailTemplateProvider,
              ISmtpEmailSender emailSender,
              IRepository<Tenant> tenantRepository,
              ICurrentUnitOfWorkProvider unitOfWorkProvider)
          {
              _emailTemplateProvider = emailTemplateProvider;
              _emailSender = emailSender;
              _tenantRepository = tenantRepository;
              _unitOfWorkProvider = unitOfWorkProvider;
          }

  SMTP mail sending also failing for me.

  Is this going to be fixed in the baseline code as I'd expect this to work without having to fix.

  Hi @Mdonogma,

  Can you share the error message you are getting ? It might be related to your email configuration.

  Thanks.
