I have updated my AspNetZero Template to the latest 4.3.1 MVC Core, Jquery, .Net 4.6.1
I am once again not able to send emails on this newer version. Previously I had this issue and I was able to resolve it by changing the UserEmailer.cs file in the Core project to implement ISMTPEmailSender instead of IEmaileSender.
Here is the link to my post on how I fixed it. #3353@c298aafa-2468-4ece-a07a-5bdd53d021f6
Here is the error:
ERROR 2017-08-18 11:21:07,043 [11 ] Mvc.ExceptionHandling.AbpExceptionFilter - The SMTP server does not support authentication.
System.NotSupportedException: The SMTP server does not support authentication.

at Abp.MailKit.DefaultMailKitSmtpBuilder.ConfigureClient(SmtpClient client)
at Abp.MailKit.DefaultMailKitSmtpBuilder.Build()
at Abp.MailKit.MailKitEmailSender.BuildSmtpClient()
So I removed all Credentials and now I am back to the UserName is Null..

Is smtp server authentication required ??
Is there another implementation ?
this application is an internal app and will run on private servers with a notification server inside the firewall. there is no authentication configured and uses port 25.
I am pulling my hair out on this one.. Seems simple but has me held up badly..
Can you advise?

hi
when you can check the SmtpEmailSender class, there's the input parameter ISmtpEmailSenderConfiguration. In this interface you can set EnableSsl=false and UseDefaultCredentials = true. This way authentication will not be done.

Sorry it took me so long to get back..
I simply changed all IEmailSender to ISmtpEmailSender and changed the namespace from Abp.Net.Mail to Abp.Net.Mail.Smtp and all is well .
Thank you so much for the support. Its always in the details..
