Someone is spoofing your email to send spam.  There's not much you can do about it except mark it as spam and let it go.

It doesnt matter which email ID you are using. The email address may be wrong or the person to whom you are sending email his inbox is running full capacity, resulting in mails to bounce.

I assume that by "unblocked" you mean that you have not blocked it.  Check with your ISP to make sure that they have not blocked it -- possibly inadvertently.  When my ISP toughened up controls, one of my friends could no longer send email to me.

I've not recieved an eamil in my Yahoo email account in two days. On any given day I usually recieve 100-150 emails, now nothing.\nI've checked in my Yahoo groups and nothing is bouncing.\nI'm also very disappointed there is no customer support in existance. If there is Yahoo has conveniently hidden it from us from accessing it!

Sadly its next to not possible... HOWEVER....\n\nIf you recall who sent you that message ask them if they can Re-send... if you are lucky they will either rmemeber, or even have it still available in their sent folder.

Some systems allow you to add special flags, one for when the message reaches the destination, and one when the message is open. When these events occur you get an e-mail back saying that this has occured.\n\nBut if yiu are sending across the internet using something like a Yahoo account then this sort of thing won't be supported.\n\nYou just have to wait a couple of days to make sure it hasn;t bounced.

If Message Archiving is turned on in your Yahoo Messenger and if you pressed Reply instead of Ok or Cancel for the Offline Message, you can restore those messages from the message archive stored in yahoo. But I presume that is not your case. So in your case, you can't recover them. Sorry.

This can have a number of different answers, but they all boil down to three possibilities.  One, you are being blocked enroute by any one of the mail gateways that handle your email.  Two, there is an infrastructure problem with DNS at your provider that is not allowing them to successfully route your mail depending on the destination domain.  Three, the recipient has set up spam filters that trash your message without their ever having seen it.\n\nIt's hard to say which particular issue is at fault, since there are no details provided.  However, examining the header field of any bounce messages you get (if any) can usually shed some light on the cause of the problem.

You need to let us know what the email system your are using (I am assuming it's yahoo, but, you might be accessing the email fro Outlook express or Outlook.  \n\nWhat is the error message?\n\nWhen does the error take place?\n\nLet us know so we can assist you.

when you hit the message it probably went to a spam/trash folder. Try to find the message again and hit the "not spam" button, so it won't be considered a spam next time the person emails you.

It seems that the person you are trying to mail has blocked e-mails from you account wantedly or accidentally. Contact him/her by phone or any other means and inform him/her about this. Ask the person to correct settings. After doing so, you must be able to send mails. If the bug still continues, contact yahoo customer care group.

Either because no one has sent you anything, or the stuff they are sending isn't getting through, bouncing back to them moments later. This blocking could be for many reasons, the most common of which is that your email account is full or offline (expired) - either your using it too much or not enough lol. Good luck.

As long as you are not receiving a MailerDaemon message in return, he is receiving the messages. However, there is no way of knowing whether or not that email was filtered out as junk/spam without asking him directly.\n\nIf you really are sending an enormous number of emails, that could cause the system to think that they are spam. It's also possible that your friend accidentally clicked on a wrong button and marked your messages as spam. However, as I said before, there's no way for a sender to know whether or not his messages have been received. This is one of the ways people are protected from spam mails.

First, check with your contact to make sure that he actually sent the message and received a confirmation that it was successfully sent.  If that is not the problem, you might not be receiving e-mail due to the following reasons:\n\n1.  The message was not addressed properly.\nThe sender may not have your correct email address or may have accidentally entered an incorrect email address.  If the address entered was valid (it belongs to someone), the message intended for you may have been received by someone else. If the address entered was invalid (not owned by anyone), the message should have been returned to the sender with an error message. \n\n2.  The message may be in the Bulk Folder.\nIf the SpamGuard option is enabled in your mailbox, it might have redirected the messages to the bulk folder.  To remove the valid e-mail from the Bulk folder, simply open the mail from the Bulk folder and click the <Not Spam> button top of the message.\n\n3.  The e-mail address of the sender is blocked.\nThe Blocked Addresses feature in some email allows you to create a list of addresses that you do not want to receive mail from. Mail coming in from one of these senders will neither arrive nor bounce, but will simply be discarded.  If you are using Yahoo mail,you can check your Blocked Addresses list by clicking <Options> located on the top right-hand side of the page, and then <Block Addresses>.Look for the email address of your friend and if it is there, just select it and click on <Remove Block>.\n\nThere.Hope this helps. =)

This is because the mails are sent to someone by using your mail id. It dont mean that they are sending the mail from your mail box. But rather they are duping your mail id. And the return Path on this mails is your ID so all the mails which are not delivered are bouncing to your mail box. To ignore those you can do following\n1. Create a filter for the mails.\n     Options -->Filters\n     Add the mail ID or subject from where you are getting this mail to be filtered and just reditrect those mail to any folder. So you wont be bothered with this mailes in you inbox. \n2. Change your password ASAP

* Possible solution\nThis error appears to be caused by some sort of bandwidth limiting system that Yahoo has put in place on their servers. Once you have exceeded your allotted bandwidth for a specific period of time Yahoo gives you this Error 999 message and doesn't allow you to access the service. People have primarily reported receiving this error when they try to access Yahoo Mail or Yahoo Groups, but other Yahoo services may also be affected.\n\nTaken from the site below... it has lots of info on that error.

if the domain was improperly spelled and does not exist it will come back as undeliverable.\n\nif the user is misspelled then it will go the the catch all inbox for that domain which may or may not accept it and may or may not be looked at depending on how they manage it at that domain.\n\nuser@domain.com
