It happens over and over — users trying to send legitimate email messages are blocked from sending because the IP address that they are getting from their Internet Service Provider (ISP) for their personal computer (or small office) is on some major blacklist, like SpamHaus. Comcast, for example, has been the focus of many of these issues. This message blocking often happens even if a user is sending outbound email through a legitimate email provider like LuxSci.
Users invariably ask:
- Why is the mail blocked even though I am sending through LuxSci or some other email provider and not directly from my ISP?
- What can I do about it?
Fortunately, there is a good reason why the blocks occur and an easy solution to them … anonymous SMTP service to hide your IP address.

So, you’re minding your own business, going about your daily tasks, checking your email, and suddenly your INBOX is flooded with a series of non-delivery reports (aka NDRs or bounce messages). But wait just a minute, you didn’t send these. How did this happen? Did someone steal your email address? How is that possible?
What has most likely happened here is that you’ve fallen victim to “backscatter“, or as it’s commonly known, bounce-back spam. As spam-detection techniques have evolved and become more accurate, the spammers have been forced to devise increasingly complicated and devious methods of getting their messages delivered. For example: email forgery.

“GrayMail” sounds like either some shriveled up husk of an email message, or the undead ghost of messages coming back to haunt me. Both concepts are not far off the mark.
Spam is easy to define – mail that you do not want and have never asked to receive.
GrayMail is legitimate bulk mail that was requested by you in the past (even if you don’t remember doing so), but which you no longer want. Graymail is generally not considered spam, yet
it represents a significant nuisance and often the unsubscribe options provided fail to work (or you may not want to use “unsubscribe” as you are afraid of inviting more unwanted email).

Email security issues and technologies are extremely complicated; however, here we intend to make the salient issues and solutions clearly understandable to all readers.
You may already know that email is not a perfectly secure communication medium; however, it might surprise you to learn just how inherently insecure email can be. Messages thought deleted can still exist in backup folders on remote servers years after being sent. Hackers can read and modify messages in transit, use your usernames and passwords to login to your online services, and steal your identity and critical information!
As the amount of crucial business conducted via email increases, so does the amount of Spam, viruses, hacking, fraud, and other malicious activity. Unless precautions are taken, email can leave you and your business open to escalating security and privacy risks. What are these risks?
