I have a small question about SPAM emails that are sent to "undisclosed recipients". Does this just mean that the server stripped the header before sending it to my account? I don't understand how it could make it to my server, let alone my email account, if nothing was specified. Does this raise any security issues?
Mail is actually routed via the RFC821/2821 MAIL FROM and RCPT TO commands, not by the RFC822/2822 From:/To:/cc:/Bcc: lines. Think - mail from this list gets to you even though you're not in the To: line. :) "undisclosed recipients" just means that somebody/something decided to add into the rfc822 headers the fact that the mail was bcc'ed to multiple people. See rfc2822, sections 3.6.3 and 5 about bcc: for more details on this.
