Sink sends email with only the first message

[akordowski]

In a .Net Core 3.1 console application the email sink sends a email which contains only the first message. All other following messages are not sent. Am I missing something in the configuration?

Code

class Program
{
    static void Main(string[] args)
    {
        var emailConnectionInfo = new EmailConnectionInfo
        {
            FromEmail = "FromEmail",
            ToEmail = "ToEmail",
            EmailSubject = "EmailSubject",
            MailServer = "MailServer",
            Port = 123,
            NetworkCredentials = new NetworkCredential("username", "password")
        };

        var logger = new LoggerConfiguration()
            .MinimumLevel.Verbose()
            .WriteTo.Console()
            .WriteTo.Email(emailConnectionInfo, batchPostingLimit: 250)
            .CreateLogger();

        logger.Verbose("Verbose Message");
        logger.Debug("Debug Message");
        logger.Information("Information Message");
        logger.Warning("Warning Message");
        logger.Error("Error Message");
        logger.Fatal("Fatal Message");
    }
}

Received email

2020-08-30 23:00:00.000 [Verbose] Verbose Message

I tested the code using the latest 2.4.0-dev-00116 package version. With this version it sends no email at all.

I got it work with the latest 2.4.0-dev-00116 package and the following code.
Increase the period to send a email only at the end of the execution.

static void Main(string[] args)
{
    var emailConnectionInfo = new EmailConnectionInfo
    {
        FromEmail = "FromEmail",
        ToEmail = "ToEmail",
        EmailSubject = "EmailSubject",
        MailServer = "MailServer",
        Port = 123,
        NetworkCredentials = new NetworkCredential("username", "password")
    };

    Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Verbose()
        .WriteTo.Console()
        .WriteTo.Email(emailConnectionInfo, period: TimeSpan.FromSeconds(300))
        .CreateLogger();

    var logger = Log.Logger;
    logger.Verbose("Verbose Message");
    logger.Debug("Debug Message");
    logger.Information("Information Message");
    logger.Warning("Warning Message");
    logger.Error("Error Message");
    logger.Fatal("Fatal Message");

    Log.CloseAndFlush();
}
