This is likely not a problem with Python or its "poplib": they are
only itermediaries between your application and the pop server -- without
special logic that may hide some messages.

One thing you can check: "poplib" uses a connection to the pop server;
it is quite possible that this connection does not see new messages
arrived after the connection was opened. Thus, create a new POP
object to check for new messages.
