retrieve email using c#?

问题

I want to retrieve emails from my Go Daddy account using C#. I tested OpenPop.NET to do that like so:

    OpenPop.Pop3.Pop3Client PopClient = new OpenPop.Pop3.Pop3Client();
    PopClient.Connect("pop.secureserver.net", 995, true);
    PopClient.Authenticate("username", "pass");

My problem is that the server does not accept the user credentials. I'm sure the credentials are OK.

I have tried the same code with my Gmail account and every thing goes OK. Is something missing that Go Daddy wants me to set?

Is there another a .NET tool like OpenPop.NET that I can use to retrieve emails using the POP3 protocol?

回答1:

I found out that OpenPop.Pop3.AuthenticationMethod.UsernameAndPassword is the missing part. I have modified the code to be following and it works.

OpenPop.Pop3.Pop3Client PopClient = new OpenPop.Pop3.Pop3Client();
PopClient.Connect("pop.secureserver.net", 995, true);
PopClient.Authenticate("username", "pass", OpenPop.Pop3.AuthenticationMethod.UsernameAndPassword);

回答2:

Port 995 is Secure POP3 which doesn't have to be supported by your mail provider.

Use 110 for regular POP3.

Its probably because your email account is not configured for Pop by default.
Go to settings in your email account and enable pop.
