E-mail security problems and the Canadian ISPs that are ignoring them

Bookmark This (opens in new window)

Over one year ago, days apart, I began to receive e-mail messages addressed to others. For weeks I worked diligently to try and put a stop to it. My requests fell on deaf ears. I receive regular reminders that it is happening still.

I began to receive many (or all) e-mail messages addressed to someone named Sandy, who lives in Ontario Province, Canada. The domain name is Eastlink.ca, a broadband access provider.  It didn’t take long to figure out that I was receiving all of Sandy’s e-mail. I wrote to Sandy, suggesting she complain to her ISP. And of course I also received a copy of the message in my own inbox. I wrote to Sandy a couple of times and never heard from her. I guess she doesn’t care – or maybe she did not receive them.  I also complained to Eastlink.ca, and heard nothing from them.

I also receive all of Brian’s e-mail, and his ISP is ica.net, another broadband access provider in eastern Canada.  I complianed to ica.net, several times, and never received a response.  I wrote to Brian also, and he responded and suggested I change my e-mail address. As if!

I also receive messages to someone at charter.net, but this user’s e-mail address does not indicate their name. I wrote to them and to Charter.net – you guessed it: no response.

Soon after this began, I wrote inbox rules to immediately delete all e-mail messages addressed *to* these user accounts that ended up in my inbox.  Now and then I look in my Trash Bin (where deleted e-mails go), and sure enough, there are still scores of e-mail messages: thank you’s for online merchant orders, FaceBook invites, e-cards, and personal correspondence.  I don’t read these messages.

Some of these messages still come to my inbox – this includes messages where the recipient is in the BCC (blind carbon copy) list. My inbox rules don’t know how to respond to these.

I wish this would stop. I’m going to write to ica.net, Charter.net, and eastlink.ca again, but I’m not expecting any response, not to mention action.

I cannot imagine that this is happening only to me. If some malevolent (or even accidental) action is behind this, then chances are that hundreds or thousands of other users’ e-mail messages are also being forwarded without their permission.

This also makes me wonder if this is happening to MY incoming e-mail: could some other user out there be receiving messages sent to me?  I sure don’t relish that idea: sometimes I receive “reset your password by clicking on this URL” messages. What if someone else receives these and decides to click the one-time link before I do? Some online account of mine could be compromised as a result.

I’m also worried about my own liability in this matter.  I’m receiving e-mail messages that are supposed to be sent to others. I don’t want them, I don’t read them, and I delete them when I see them. But what if I receive messages containing personal medical information, for instance?

There are several possible causes for this inadvertent e-mail forwarding:

  • Malware, tampering, or compromise of ISP e-mail server.
  • Compromise of individual users’ e-mail accounts, where attacker inserts rules to forward mail to me (and maybe others).
  • Malare or compromise on individual users’ computers; this may be true if users use workstation-based e-mail software such as Outlook, Outlook Express, or Thunderbird.

There may be other potential causes, but I cannot think of any more.

If malware or a human intruder were behind this, what is their gain? What is the benefit for an intruder if someone’s e-mail is forwarded to someone who lives 3,000 miles away?  If the intent is to harm someone, who does it harm? If the intent is to harm the individuals whose e-mail messages are being forwarded to me, then I can think of several more malicious ways to harm them.  If the intent is to harm me, I don’t see how this harms me.

Use ReadNotify to confirm addressee receipt of e-mail

Bookmark This (opens in new window)

If nothing other than simple efficiency, most of the major e-mail services (Yahoo, MSN, Gmail, Hotmail, AOL, etc.) do not support e-mail return receipts. Even when a sender uses a tool that does assert return receipts, such as Outlook or Thunderbird, many of these services simply ignore return receipt requests and do not create them and send them to senders.

ReadNotifyThere is an opportunity to change all that. The tool ReadNotify restores the ability for a sender to know whether a recipient has read an e-mail message. The beauty of this is, it works even for the email services that do not support traditional return receipts.

ReadNotify has a 30-day free trial. After that, choose from either the Basic (US$24/yr) or the Premium (US$36/yr) subscription plan.

If you really need to know whether certain e-mails are actually read by their recipients, ReadNotify may be for you.

Certified Return Receipt

A really nice feature available in ReadNotify is digitally signed return receipts. This option will digitally sign your email and insert a timestamp certificate. This certificate irrevocably links the body and headers of an email to the date and time they were dispatched – and may be offered as court admissible evidence if required.

Other Features

ReadNotify supports several other features, including Ensured (stored on ReadNotify servers until the recipient reads it), Retractable (body of message can be retracted), Self Destruct (message can be destroyed prior to user reading it), Block Print (prevents user from printing – well it slows them down anyway), Invisible (recipient will not be aware of your tracking), and more.

Caution: ReadNotify was apparently used to track e-mails in the HP e-mail scandal. Seek legal advice if you are unsure whether your use of ReadNotify is legal.
