My IT department has informed me that the SMTP server is configured not to use authentication. I have cleared the user and password, but cannot get the system to send email - on windows or linux.

Is it possible to send email without providing an user / password to Mailkit?

The error message received is:
The SMTP server does not support authentication.

The stack trace:

My colleague informed me that the password I was sending in the request body first needed to be base-64 encoded using the utility found here:

After encoding my password, the request is now working as expected.

I've followed the documentation for generating a token, but am not able to get the password to validate.

I have verified that the user configured in Manage api users matches an active user account, and that the password matches the params posted to the api. I am able to step through the code, and see the apiuser record is retrieved via the email address.

However, on line 29 of the LoginValidator, the encrypted values do not match, resulting in a 400 response with the error "User not exists or password is wrong":

Grand.Web.Areas.Api.Validators.Common.LoginValidator line #29:
userapi.Password = "WVv3K2+inlyXrlVaJ6ML39iBqXfjNN/k"
encryptionService.EncryptText(password, userapi.PrivateKey) = "43OCLnIRcilrHsOHpOn4nw=="

I'm using Grand Node Version 4.4
