For real security you should validate certificates when you connect to servers and not blindly accept any SSL ceritificate. If you don't check them then you are still vulnerable to MitM attacks. That is, however, too off-topic to discuss here. See Wikipedia: Man-in-the-middle-attack for more background information. Clients like mIRC and XChat will show a popup prompt when a new (unknown) SSL certificate is detected.
