Can I Block Sendmail From Sending Ndr

• The Can Spam law covers email that's primary purpose is to advertise or promote a product, service, or website.
• If these types of emails contain false or misleading information they are in offense of the can-spam act.
• Usually, you can easily understand it is spam just by reading the email.
• Although this can oftentimes be more convenient, it will mean the spammer won't have any legal action taken against them.
• By monitoring spam sent to these addresses, analysts can detect and study ongoing spam attacks.
• Spam can carry virus or link to sites that contain viruses.
• Most people are more concerned about viruses because it affects much more than spam, but it is important to understand that simple spam can introduce a virus, and it could even cost you your entire computer!If a spammer can set up his own authoritative name servers for his website domains, he can use these to rapidly change the apparent address of his websites among large botnets of compromised home computers.
• Ping is not extremely useful by itself in spam investigation, but can be used to determine whether a host you are interested in is currently online.
• If you can see how ineffective our current spam legislation is, you might think spam will always be a problem, at least as long as we allow useless laws to regulate it.
• Spammers can use escapes even when they aren't needed to disguise portions of the message or the origins of their network resources.
• Virus and trojans: check your computer for virus's and trojans that can make your computer into a mindless zombie spam emailer.
• Read privacy policies before disclosing your email address - don't register your email address on a website unless you know for sure that you can later opt-out from any emails they send you.
• You can sometimes track spammers to particular ip addresses that they use (for sending mail or for maintaining websites); you can then use whois lookups to determine the owners of the netblocks in which these addresses appear, and then report the abuse to these parties, or to the upstream provider responsible for having sold the block.
