I use NLog with next configuration:

Answer 1

I know that my answer is not exactly answering the question, but the most difficult thing is to find the right target and cast it properly, then we can access any properties. I also didn't find a question that would fit my answer thus posting here...

This method will work even if you have set async="true" (i.e. your target is wrapped by an AsyncTargetWrapper or any TargetWrapper) in your NLog XML configuration:

Using NLog Version: 3.1.0.0

Runtime Version: v4.0.30319

    private Target FindTargetByName(string targetName)
    {
        if (LogManager.Configuration == null)
            return null;

        Target t = LogManager.Configuration.FindTargetByName(targetName);

        if (t is NLog.Targets.Wrappers.WrapperTargetBase)
        {
            var list = LogManager.Configuration.AllTargets.ToList();
            t = list.Find(x => x.Name == targetName + "_wrapped");
            return t;
        }
        else
        {
            return t;
        }
    }

Usage for MailTarget named emailError

var emailError = (MailTarget)FindTargetByName("emailError");
emailError.SmtpServer = "" //you can set or get
