I receive mail all the time and in the "to" box, it says "undisclosed recipients@"...I´d like to do the same, as several of the people I write to don´t like their addresses disclosed or in view for others to see.  Thanks!

Use the BCC: field. It is 'Blind Carbon Copy' or 'Blind Courtesy Copy' (whichever you prefer). Regardless, any receipint in the bcc field will not be shown in the e-mail.

The contacts in  your email account will work from email address for most programs they are not linked to your email address they are linked to the program.\n\nAs I don't know what program you use I will keep this generic.\n\nFrom your new email account send an email to everyone at once but blind copy them thats the bc catagory so you protect their privacy and in the RE line simply put this is **** my email addy has been changed to this\n\nThat will show up in their in box so they will know its safe to open and not from a stranger.\n\nThen you can put what you want in the body of the email.  \n\nSometimes the simplest answer is the best answer.....

It's something the person you're sending to has to do. When they filled in their profile and submitted their email address, they never verified the address.

Sometimes there is a link in the mail from advertisers affording you the opportunity to opt out of them sending you emails.  As for individuals, I know that Yahoo has this feature where you can block emails or maybe you can report this mail as spam.

Email adresses are easily forged. Chances are that an email you got from that address wasn't actually sent by that person, especially if it is spam. Just don't give out any personal information on the internet, and you will be fine.

those are spam mail.. \n\nUnwanted mails should be labeled as "marked as spam" to prevent receiving those emails in the future.\n\nand if possible, try minimizing exposing your email address to non-trusting websites

Don't reply to the emails.  You should have the option to mark their emails as spam or junk.  I've had to change my email address before because of stuff like that.  One thing to remember, don't send mass emails and ask your friends to not include you in mass emails.  Mass emails spread your email address all over the place, and my experience has been that lots of spam come to me after I was part of someone mass email.

I get similar e-mails all the time.  The only thing I know to do is to forward them to the below address.  Honestly, I don't know if it does any good, but that's what I have read.

It usually tells you which address it is. Then delete it as it is on spam/blocked list of your mail server. Sometimes you servers block attempt to send to multiple addresses as well...\n\nAsk you intranet administrator about mail server policy

Yahoo does give that option to each person whether or not to show his/her email address.  In order to obtain that person's email address, you'll have to take the block off of yours.    \n\nEven if you were to send an email to that idiot of a person, he/she probably wouldn't care or be smart enough to understand your email.  Plus I wouldn't want that idiot to know my email address.  They'll just act stupid by bombarding your email box with more stupid things.

It would be complicated, but you could always check your 'Sent' folder and outbox for hints. Also, you could mail round your contacts and ask if they have had any odd emails from your account. And, of course if you suspect or discover something, change your password. :D

Well you can't! If a message reached in the Bulk folder this doesn't mean is guaranteed to be spam, but it probably is. If you consider it's not spam then you can move it to your inbox and I think the next time you receive a message from the same person it won't be put in bulk anymore. Depends though...

This is clearly a big thing and needs addressing, I would surggest emailing through the "contact yahoo" it might be best to send it as a technical email because i find that emails such as the one you will send are not always read on passed on simply discarded where if the think it is technical they will read it and have to pass it on. Hope this helps!

Carbon Copy and Blind Carbon Copy.\n\nBcc keeps those addresses hidden so that the CC recipients can't see who received the email.

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.

No - that's what BLIND copy means.\n\nOnly the sender knows who it was sent to. You may be able to trace the sender based on the IP in the mail header, but it's more likely that the mail was sent by a spam zombie.
