I'm not 100% sure, but I believe the answer is no.

I don't think so either. Your email should just go straight into their "deleted" folder but you wouldn't know that.

It depends how it's blocked and the method of blocking. Sometimes you'll get a notice but most often you won't.

Just curious - why would you be sending email to someone that's already blocked you?

Or do you not know if you've been blocked?

If you generate the email within your own computer with an email utility such as Thunderbird or Windows Mail, in many cases you will get a notification of undeliverable mail from your ISP.

However, if you write a reply within a forum, you may or may not receive a reply about a blocked or non-existent address. Most likely, the 'failed' message you see is within the forum and is not an email sent to your email service.

When you do get a 'failed' email message, there will be a lot of computereze in the message and it will take some slogging through the verbage to ferret out the part you wish to see.

I don't know about you, but I have AT&T and whenever my emails are not delivered, I get a message from them.

The only time I've gotten a message from my email provider about an undeliverable email, the address has been wrong. I've never gotten one that indicated the receiver had blocked my messages. That doesn't mean anything as I don't know if anyone has ever blocked me. I do block unknown senders that I suspect as spammers by directing their emails to the junk or spam box. So, based on my experience, if you get an undeliverable message your email did not go through. Otherwise, it went somewhere and the recipient either deleted it or chose not to reply. I have yahoo and hotmail for the two accounts I use.

I blocked someone because she persisted in sending me multiple forwarded mail, full of dozens of other people's e-mail addresses. I don't like to receive these things because I got a virus this way once.

I usually will respond the first time someone sends me one of these things and ask them to please use the "bcc" function in their address book for all their addresses, strip out all the previous e-mail addresses in the multi-forwarded message, and then put their own address in the "to" box. In this way, everyone who receives this does not see anyone else's e-mail address.

Spammers just love to get these forwarded e-mails because it gives them more addresses to add to their list.

But anyway, I asked her as nicely as I knew how. Sometimes people get mad at me and won't e-mail me at all after that. Sometimes they just ignore my request. Seems to be no happy medium and I'm at a loss to explain why. Good manners dictates that before you add someone's e-mail address to your forwarding list, you ask them if they mind. Many people do not have time to read a lot of the stuff that circulates and prefer not to get them but are uncomfortable about saying so for fear they will insult the sender.

In this instance, she disregarded my request and in fact started forwarding even more stuff to me. She was a lady from my church so I decided the best thing to do would be to block all her e-mails.

The next Sunday at church she came to me and asked my if I was mad at her. I told her I was not. She then said, "Then why did you block my e-mails?" So, I was disappointed to find out that, in my case, using Outlook, there was, indeed, a message sent to the sender that their message was undeliverable because the receiver had blocked them.
