How Do I View the List of BCC’ed Recipients on an Email I’ve Received?

//
I want to find the list of “undisclosed recipients” of the email I’ve received. Is there a way?

No.

“Undisclosed recipients” is often placed in the “To:” line by email programs when the message being sent has no entries in the “To:” or “Cc:” lines. The sender has used the “Bcc:” feature of email to send the email to one or more people without revealing who they are.

So, how do you find out who they are?

Why Does Email Bounce?

//
Sometimes, my email bounces. Every so often, I’ll send a message, and a short time later, I’ll receive a reply saying that the email failed to go through. Why does it happen? And how do I fix it?

Well, I’m afraid there are many reasons why mail can bounce. In fact, there are so many ways email can fail, sometimes I’m amazed it works at all. But it definitely works most of the time, and one of the ways that it works is that very bounce message that you get.

You see, there’s gold in that bounce message. It’s not only telling you that your message didn’t go through, but if you look a little closer, you’ll see it’s trying to tell you why.

What Do Spam Filters Look At?

Someone commented to me that his spam filter was pretty useless since the spam he was receiving kept coming from different email addresses. The implication was that this person believed that the “From:” address is the only thing that spam filters check.

While that’s possible, it’s also very rare.

These days, spam filters are incredibly complex and sophisticated pieces of software that check much more than you might think.

Why Is an Email Address Sometimes in Angle Brackets?

//
Every so often I see email addresses listed like this:

Name <myemail@hotmail.com>

or even

myemail@hotmail.com <myemail@hotmail.com>

What’s it all mean, especially that last one?

Well, the last one is someone just not filling in some information in their email program like they’re supposed to.

But in general, that format is just the email protocol recognizing that most people don’t think in terms of email addresses; they think in terms of names.

I got two identical spam messages from two friends. Which of us has been hacked?

//
Leo, I’ve received two emails from two different friends, both of which have the same link in them. Hotmail threw both of them into junk mail area so I was suspicious and didn’t click on the link and deleted them. But I was wondering, have they been hacked? Or have I? Should I warn them or start looking into my own vulnerability?

Without looking at the actual message source (meaning the headers that you don’t normally look at) it’s nearly impossible to say. It could be you, but ultimately, I don’t think it’s likely. It could be them. Or, believe it or not, it could be nothing at all.

How do I tell who really sent an email?

//
Leo, how do I tell who really sent me an email? And I mean their real name, location and telephone number if at all possible?

This is super simple.

You can’t.

Now, I’m assuming you don’t work in law enforcement. They police can get a lot of information; more than you or I ever could. Most of what I have to say will look at the various pieces of data that are associated with an email, and explain how easily they can be completely falsified. I can think of one scenario where you might get lucky, but that’s only if the sender isn’t being particularly careful.

How can I prove that I didn’t send a particular email?

//
A guy received an email apparently from my email address (a Yahoo account), but I’ve never sent such a mail. Now, I received a letter from the attorney of this guy accusing me of harassing his client. The  email in question was sent in April of last year. What can I do to help clarify this misunderstanding?

As it turns out, making email that looks like it came from you is really easy. Spammers actually use “From” spoofing all the time to do this.

Surprisingly, proving that it was not from you might be a little harder.

How Do I Tell Someone They’re Entering Their Email Address Wrong?

//
I’m receiving email confirmations from some commercial site; some confirmations of orders, etc. From the content of one of these, I know the person’s name and date of birth as well as the fact that they live in England. All of the emails are of the “do not respond” type. I suspect that someone entered their email address incorrectly at some point and would like to inform the intended recipient of the issue so that it can be corrected, but I’m unable to find a contact for them. The last name is the same as mine, which makes it a little bit more complicated.

This is one of those very interesting, but admittedly frustrating problems that we face online almost daily. It’s something that I’ve run into with Ask Leo! and when we were running my wife’s business.

The problem is very simple. When somebody gives you their email address as contact information and they get their own email address wrong, how do you contact them to tell them so?

The bottom line is that unless they’ve given you additional information like a phone number, you can’t.

Why is email I’m sending being received by someone I’m not sending to?

//
Hi, Leo. My business sends periodic email invitations out to our patrons that sign our guest registry with just their name and email address. Somehow, there is someone that’s getting the email, but he is not in my contact list. And he’s getting pretty upset. Now, I can’t blame him. I’ve triple-checked my contacts and his name is not there. Today, I sent an invitation and manually typed the names. As always, I asked that if people want to be removed, they just reply with “remove” in the subject line. I got an email from this person to be removed. I’m beside myself on what to do. Any suggestions?

To be honest, this is a really tough one. I run into this all the time. On the various email lists that I manage, I’ll end up getting a bounce message for an email that’s not on my list.

And while I have some ideas as to why, there’s little I can do.

Why do I get spam that’s not addressed to me?

//
Why do I receive junk emails that are not addressed to my specific email address but to several subtle variations of my address? Why do these emails get delivered to my address when they are not addressed specifically to me? And how should I most properly dispose of them?

Spammers do everything they can to get their garbage in front of you, and that means using and abusing every tool at their disposal.

One of those tools is something that’s available to you and me when we send messages as well.
