I have an automation in Pega 8.0.2017. It sends emails without any issues. When I upgrade to version 19 I start receiving exceptions. The VDI and SMTP setup have not changed. The logic still works on Pega 8 (see screen shot).
System.NotSupportedException: The SMTP server does not support authentication.
at MailKit.Net.Smtp.SmtpClient.Authenticate(Encoding encoding, ICredentials credentials, CancellationToken cancellationToken)
at MailKit.MailService.Authenticate(String userName, String password, CancellationToken cancellationToken)
Is there something in the new component that forces it to authenticate? Is there a way to disable it? I don't see any options that differ in the smtp component within Studio 19.1 that would force it to not authenticate.
There were a few updates to the SMTP component in 19.1. If you are using the initial build, it may have problems as there was a fix released relatively early (in build 3). If you are using the latest build of 19.1, then there haven't been any fixes since May of this year. What build of 19.1 are you using?
