Seems like the problem is that the server after getting the wrong password closes the connection and this way $pop gets undefined?

No, you forget to quit and close the connection, which should be done even if there is a login failure. If you do quit and close the connection, the error message will be gone :) (just move it outside the if-statement)

# print number of msg or complain about failed login
if (defined $a[0])
{
   print "Messages: $a[0]\n";
}
else
{
   print "Login failed.\n";
}
$pop->quit();
