Feedback Loops: Monitor your bulk email reputation

Wednesday, November 2nd, 2011

Many major Internet Service Providers (e.g. AOL, Hotmail, MSN, Comcast, etc.) have FBLs “feedback loops” for reporting SPAM complaints by their users.  I.e. if a user “marks a message as Spam”, information about that message and the fact that it was considered “Spam” by the recipient can be sent back to the originating email server, for example LuxSci.

LuxSci has participated in feedback loops for a long time .  Now we have greatly extended our participation by:

Text Messages are Faster than Email, but not Instantaneous!

Wednesday, May 4th, 2011

We have discussed how email messages should not be expected to arrive instantly.  This naturally brings to mind “text messages” (aka SMS messages) that people send to their cell phones.  These are commonly expected to be delivered “instantly” — but that is also not always the case.  While text messages are generally very fast, and usually more quickly delivered than email messages, they are not always “instant”.

Better Forged Email Filtering with Improved SPF Support

Wednesday, June 23rd, 2010

It is an extremely common and annoying practice of spammers to send you email that is from yourself or your colleagues or friends.  I.e. “forged email”.  We discuss this problem in the article: Save Yourself From “Yourself”: Stop Spam From Your Own Address.

Users of LuxSci’s Premium Email Filtering service now have a new and very powerful weapon to stop this kind of spam — “SPF-enabled allow list entries”.

This feature allows you to easily receive protection from forged spam messages while at the same time ensuring that legitimate messages sent between users in your organization are not filtered or caught as spam.

Protecting Yourself from Email “Web Bugs”

Wednesday, September 30th, 2009

Web Bugs are images in HTML-formatted email messages that, when viewed, tell the sender of the message that you read the message.  This mechanism of obtaining an essentially covert confirmation that (a) your email address is valid, (b) the email got past your filters, and (c) you actually read the message, is pervasively used by Spammers to identify what addresses are reading their messages.

Mitigating Threats To Your Email Security and Privacy

Sunday, March 8th, 2009

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?

Stop the Backscatter Spam with a Custom Filter

Monday, December 15th, 2008

We recently talked about the problems created by backscatter or bounce back spam.  I.e. the pain caused by getting lots of "delivery failure" messages for messages that you never sent, but which arrive at your door anyway. One of the solutions we have provided for dealing with backscatter, if you have this problem, is to create a custom email filter in your LuxSci WebMail interface that will delete or save all bounce messages.  While this works well, it also has a drawback.

Where did all my Spam go?

Friday, November 14th, 2008

Internet service providers Global Crossing and Hurricane Electric shut down the San Jose, CA, web hosting provider "McColo" on Tuesday after it was determined that the ISP was aiding criminals in the sending of Spam, perpetrating online fraud, and providing access to child pornography.  McColo was used by some of the most active and prolific spammers in the world; the suspension of its services has resulted in a 75% decrease in spam, worldwide!
