How do I get 'Undisclosed-Recipient' message when I send an E-Mail?

put the addresses in the BCC field (blind carbon copy). To send the message you do need to have at least one address in the regular "to" field. I usually put my own.

somebody put her address in the "BCC" field of an e-mail. People who receive "B"lind Carbon Copies of an e-mail don't show up in the "To" or "CC" fields (well, actually they don't show up at all)

When the message comes up, just delete the text of the message that contains the e-mail addresses of all the previous recipients.  If each person who forwarded a message did this, the long list of people wouldn't be there in the first place.  :-)

here is a trick that i used for hacked e mails to not let the people who were hacked to know that i have cheked thier e mails,, u can use it to know that someone has read ur e mail,\n when u read ane  mail,, than after reading select e mail and than clcik MARK AS and than cllick UNREAD ,, so tahts mean MARK AS > UNREAD  , after that this  e mail would appear like newly arrived e mail, after u can sloe ur e mail,, next time u open ur e mail, if ur e mail still apears as UNREAD (mean newly arrives mail) so tahts mean nobody has read ur e mail, and if it appears like READ e mail (mean old e mail) tahst eman someone chekced ur e mail,, hope this helps\n(NOTE: its a matter that the other one is clever than us and he also marks e mail as UNREAD after reading ti again,, hihihihi)

Probably just a spammer.  Emails can be easily "spoofed" - this is, fake senders/subjects/dates can be sent out via SMTP very easily.  I'd just chuck it in the SPAM pile and not worry about it.  Don't even both opening them if you notice stuff like that.

Most email applications have a spam folder. Most things marked as spam are automatically sent to that folder upon receipt.\n\nGo to that folder, and find the message in question. Usually there are buttons soemwhere, one of which says "not spam". Meaning, if you highlight the message and click this button, it will no longer be regarded as spam.\n\nYou should find something very similar to this for whatever application you are talking about.

Please give more details. Are you using a web interface, an email client? What email service are you using? What OS you have? etc.

might be a problem with the exchange server, if you are sure you have the address right. they may also have settings to block email with no subject line.

You could be on the "bcc" list of these emails. In this case you are just secrectly copied. Nobody except the sender will know.

Everything in the bcc line stays hidden.  The recipient's full message headers will only have their email address (usually not in the To line but near the top in something like Apparently-To: email@email.com -- something like that.\n\nSo to answer your question, no.

If you are using the free yahoo mail service, then every email that you send and receive is scanned by Norton antivirus. \nThere is no safety agains spam as of now, except that all the unsolicited email will be dropped off in your bulk mail folder.

Even though technology has advanced far enough to have people access various entertainment and aid applications, there is no legal way to know if a person recieved their Yahoo! mail, atleast none that I know of. True, they may send you a reply if it is appropriate, or they will notify you personally, but none have been devised to do so.

Select BCC, which is Blind Carbon Copy.\nThis hides the email addresses.
