Hello Support,

Sending an email (PEC) with 15 attachments total 40 MB sending crashes and this error appears:

Try commenting out the code you have in event handlers, as a failure seems to occur somewhere there.

Hello Igor,

Download this zip file (40MB): http://www.juris.it/Aggiornamento/Test.zip
After downloading send an email with all attachments.

After 2 minutes you see this exception: InnerException message follows: '-29' is not a valid value for 'Value'. 'Value' should be between 'minimum' and 'maximum'. Parameter name: Value

How can I fix this error?

Regards, Lello

Thank you. The issue is not reproduced though. I've used the following code:

Code:

MailBee.Global.LicenseKey = "MN800-****-****";

Smtp mailer = new Smtp();

mailer.Log.Enabled = true;

mailer.Log.Filename = @"c:\temp\log.txt";

mailer.Log.Clear();

mailer.From.AsString = "sender@domain.com";

mailer.To.AsString = "recipient@domain.com";

mailer.Subject = "Test With Attachments";

mailer.BodyPlainText = "A lot of files were attached here!";

foreach (string file in Directory.GetFiles(@"c:\temp\files\"))

{

    mailer.AddAttachment(file);

}

mailer.SmtpServers.Add("mail.domain.com", "sender@domain.com", "PaSsWoRd");

mailer.SmtpServers[0].SmtpOptions = ExtendedSmtpOptions.NoChunking;

mailer.Send();

And c:\temp\files\ is the directory the archive was extracted to. It took a while but the message was sent out and arrived to the recipient just fine. See if the code works for you, as it still looks like the issue is specific to your own code.

Hello Igor,

I use SMTP With TLS / SSL

Please try again in this way:

// Create an instance of SmtpServer object.
SmtpServer server = new SmtpServer();

server.Name = "*****.***.*****.**"
server.AuthMethods = AuthenticationMethods.Auto;
server.AuthOptions = AuthenticationOptions.PreferSimpleMethods;
server.AccountName = "*****@***.*****.**";
server.Password = "my-SmtpPassword";
server.Port = 465;
server.SslMode = SslStartupMode.OnConnect;
server.Timeout = 70000;
server.SmtpOptions = ExtendedSmtpOptions.NoChunking;

//Add to Mailler...
mailer.SmtpServers.Add(server);

I am a suspect:
It could be the progress bar?

I can't use that server if I don't have an account there.

And yes, this looks like the problem with handling events, progress bar is a typical case of that.

Hello Igor,

You can try another server with TLS / SSL ?

=====================
NOTE: I wrote by mistake my credentials. Please can you delete from the forum?

I can try that later. But I'm 200% sure this is unrelated to the actual problem. It just can't cause the error message you quoted earlier.

Sure, done.

Hello Igor,

This try-catch solves the problem...

======================================
    // MessageDataChunkSent event handler. Fires each time a chunk
    // of the message data is being sent to the server.
    private void OnMessageDataChunkSent(object sender, SmtpMessageDataChunkSentEventArgs e)
    {
        int percent;

      ////
      // omissis....
      ////

     //This try-catch solves the problem
     try
     {
        // Update progress bar.
        progressBarSending.Value = percent;
     }
     catch { }
    }
