Having Problems Sending Email Because Your ISP is Blacklisted?

Wednesday, October 9th, 2013

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.

Bounce Back & Backscatter Spam: Who Stole My Email Address?

Tuesday, September 24th, 2013

spamSo, 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.

Web Forms Reduce Spam and Optimize Business Processes

Wednesday, July 10th, 2013

Businesses of all sizes use general purpose email addresses, like info@company.com or support@company.com, as conduits for information, Support, Sales, Billing, and other requests from customers.  On the surface, there is an apparently very good reason for this: many customers appreciate the simplicity of being able to send an email message.  It’s best to be as flexible as possible and reduce the time that the customer must spend to get a response, right?

There are actually many significant downsides to accepting general customer requests via email; downsides which can actually cause friction, slow the response process, or result in missed opportunities.  We will cover many of these issues, below.  The solution, is to use targeted specific web-based forms to collect customer requests; we will also discuss why this is a better approach.

Graymail “Spam”: What it is and how to get rid of it!

Tuesday, November 13th, 2012

“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).

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.
