Sends a command to the POP3 server to keep the connection alive.
MailBee.NET (in MailBee.NET.dll) Version: 12.2.0 build 630 for .NET 4.5
Public Function Noop2 As Boolean
if the method succeeds; otherwise, false
The developer can use this method to keep the POP3 server from timing out the connection
when there is no real activity. This method actually sends STAT command to the server.
This seems to be more reliable solution than the standard NOOP command which is ignored
by some POP3 servers.
