Only class 1 certificates are free.<p>This is a great service as it allows me to setup secure IMAP, SMTP, Jabber, etc. without having to pay a third party money for this extra security, and without having to bother my users with installing my self-signed root certificate (StartSSL’s certificate is known to OS X and browsers except IE and Opera).<p>I don’t see how free class 1 certificates help scammers, phishers, and similar.
