We cannot find the problem from c# code, should change some settings to exchange server? Thx!

CODE:

Pop3 pop = new Pop3();
pop.Log.Enabled = true;
pop.Log.Filename = @"C:\mblog.txt";
pop.InboxPreloadOptions = Pop3InboxPreloadOptions.Uidl;
pop.Connect("mail.xxxx.com", 110);
if (pop.IsConnected)
{
    pop.Login("janet", "ppp");
    MailMessage message;
    string[] messageUids = pop.GetMessageUids();
    message = pop.DownloadEntireMessage(1);
}

This code works. But we have to download the Uids before download EntireMessage. Thx!!!


CODE:

Pop3 pop = new Pop3();
pop.Log.Enabled = true;
pop.Log.Filename = @"C:\mblog.txt";
//pop.InboxPreloadOptions = Pop3InboxPreloadOptions.Uidl;
pop.Connect("mail.xxxx.com", 110);
if (pop.IsConnected)
{
    pop.Login("janet", "ppp");
    MailMessage message;
    //string[] messageUids = pop.GetMessageUids();
    message = pop.DownloadEntireMessage(1);
}

Please make sure the problem reproduces with the current version 6.10. If it does, please provide the log from v6.10.

Thank you. I see 3 seconds delay between [10:28:33.27] [INFO] Downloaded entire message (index=1) and [10:28:36.78] [INFO] Will download entire message (index=2).

What happens in between? What happens if you download both mails in a single command Pop3.DownloadEntireMessages(1, 2)?

BTW, is it possible to get a test account?

Regards,
Alex

For the 3 seconds delay, because of I was tracing the code step by step.

I tested DownloadEntireMessages(1, 2) and got same error.

I asked our client to setup a text account, I will forward to you ASAP.

Thanks!

Looks like forcing plain-text authentication prevents Exchange from breaking the connection.

Code:
pop.Login("user", "pass", AuthenticationMethods.Regular);


we'll continue testing to find out if it's possible to have secure auth fixed. It works with Exchange 2010 and 2007 but this one is probably of a different version.

Please keep the test account working. Thanks.

Alex

Testing with Outlook Express showed the same problem. Using secure authentication makes this Exchange installation go wild.

Hi Igor
I got the same error while trying to download a 1MB attachment using QuickDownloadMessage method.
Any recent solution?

Try using the full procedure (create Pop3 object, and so on). If the problem persists, enable logging and post your log file. Thanks.
