I've deleted all messages from my Gmail mailbox using the following code:

Pop3 client = new Pop3(); 
client.Connect("pop.gmail.com", Pop3.DefaultImplicitSslPort, null, Pop3Security.Implicit);
client.Login("username", "password");
Pop3MessageCollection messages = client.GetMessageList(Pop3ListFields.FullHeaders);
Console.WriteLine("Processsing {0} messages...", messages.Count);
foreach (Pop3MessageInfo msg in messages)

The first execution successfully processes all messages, any next execution finds no message in my POP3 mailbox.

However, when I connect to the Gmail through their web pages, the deleted messages are still visible in my Inbox.

You have to specify on Gmail what to do with messages deleted through POP3 protocol. Log to your account on www.gmail.com and change the settings according to following instructions:
