What are the occasional e-mails I receive that have no Sender Name (it's blank) and subject is [none]?

Don't open it. It's spam. If you open it, they know they reached a live address.

When you get a MAILER-DAEMON@whatevercompany.com message in your inbox, the server at that company is informing you that it is returning your message because of some failure. The "to" e-mail address may no longer be valid, or there may be a problem routing the message to the appropriate mail server. Your domain name may be on a blacklist, and the server is refusing all incoming messages from it.\n\n*Make sure that you are typing in the correct email address.

?? is it the number of unread/mew mails in your mail box?

try checking under bulk mails, maybe their mails are considered as spam

Try this...\n\nGo to "View" (up above), "encoding" and click on auto if it's not on. If it is, then go to "more" and then go through all that are there (unless you know which one it is).\n\nSounds like the e-mail you got was written with different characters (like if it's from overseas). So this solution should help

You sound just like  the Mailer_Daemon that notifies me of a letter that failed to send. It ends usually with a "sorry it worked out this way" which is kind of creepy if thats you.

you may have accidentally marked that address as junk email, check your filters would be an excellent start, possible use a new email address like one on yahoo to double check they are in fact replying to you

There are so many reasons that can lead to such problems,\n1, it could be that the address is blocked from not receiving mails.\n2, It could be a scam, forwarded by a SMTP Server.\n3, It could be that the server is unavailable\n4, It could be that the persons mail box u are trying to send that mail is field up and the person need to delete some masseges b4 new ones can enter.\n5, It could be that the persons mail Box have been deactivated.\n6, It might be an Auto Response.\n7, You might be making a mistake in the address.

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.

I think it is because either they don't have your address or nothing to send to you

its either blocked or not a proper e-mail address

i got one too, and have in the past... there's nothing in it... it's entirely blank, though it may have had some tracker in it that was activated when i opened it because after i got a lot of spam... i don't recomend opening it

I'm not exactaly sure, but from the name, it sounds like a mail server, and I know that my computer gets a "error 403: Forbidden!" on it.

Just click the line "1 unread message", or mail or email around that line, probably you will be lead to a page to log in or see the title of that email.

If there is not any,  there ought to be one. To begin with: no hiding behind assumed names, nicks, and numbers/signs...!  Communications having become so quick, yet the emailers have no time for greetings, no time to write full words, no time to compose a grammatically complete sentence. The language is being ruined. The manners are put to dust. The etiquettes forgotten. The spam becoming a profession.
