* BUG: Process stream correctly detects when something has been really read during a Read event. [GB.NET.SMTP] * NEW: SmtpClient._NoGreeting is a new property that tells not to read the SMTP server greeting. This is needed, because with TLS authentication, openssl does not print it. git-svn-id: svn://localhost/gambas/trunk@2865 867c0c6c-44f3-4631-809d-bfa615b0a4ec
