• This error usually occurs if your credentials are not true, please check the email address and password that you've provided.

• As I see you want to use the Gmail SMTP server. If you want to use Google's SMTP server settings and send emails via Gmail, you should confirm this first, if you haven't yet.

• If you are sure about your email address-password and confirmed the related section in Gmail, can you try to set your password by using the SettingManager's SetGlobalAsync method :

public override void OnApplicationInitialization(ApplicationInitializationContext context) 
{ 
     var settingManager = context.ServiceProvider.GetService<SettingManager>(); 
     //encrypts the password on set and decrypts on get(IStringEncryptionService) 
     settingManager.SetGlobalAsync(EmailSettingNames.Smtp.Password, "your_password"); 
}

I am not overriding any method,i am using abp inbuilt registration where i got this error on server.

And what's your SMTP code?

eg:

hi

Can you try to disable ssl?

And what's your stmp code?

i already try that,but same error is thrown

it's through 500 error

What's the error detail?

Hi @kapil, can you set SecureSocketOption as SecureSocketOptions.SslOnConnect:

Configure<AbpMailKitOptions>(options => 
{ 
    options.SecureSocketOption = SecureSocketOptions.SslOnConnect; 
}); 

SslOnConnect -> The connection should use SSL or TLS encryption immediately. (http://www.mimekit.net/docs/html/T_MailKit_Security_SecureSocketOptions.htm)

I Solve this error now i am able to send mail but using same credential(In Email Settingmanagement) on server its not working. it's through 500 error on register.(I am using inbuilt registration(Account Pro) modules of ABP)

No, we have used inbuilt module of abp for registeration. but i got error on server.

i am able to send email through this code :->https://github.com/abpframework/abp-samples/tree/master/EmailSendDemo

but not able send mail from ABP Project on server using same credentials.
