You need to just reopen the account. You would've lost all mail and folders in it, but once you re-log into it, it will begin receiving mail again. Like, with the response to this question will be an email...

There's a good chance the email address you are forwarding it to is invalid, closed (possibly filled up to its capacity) or no longer exists. There's also the rare possibility of server failure. You have to read the details in the email header and try and trace the path it took. There usually is a message why an email is returned to you amongst those details.

Chances are LSU assigns a storage space limit to your inbox. Once you reach the limit, you won't receive mail until you delete some emails. Try deleting from you INBOX and then your deleted items. I can't guarantee this is the problem, but it is worth a shot.

If you added the address information to your addresses it should come up. It doesn't recognize an email that is not added to your addresses list.

It's gone. You might get the same address again if no one else is using it, but the past email is long written over on that hard drive.

This is not that uncommon, someone used your address as a reply to address in a spam campaign. Irritating but not too much you can do about it.

Some e-mail services let you add spam to a spam folder which gets returned to the sender saying somthing along the lines of "This address was not valid" that is the best way to get removed from the list.\n\nif you mail them back saying you would not like to recieve their e-mail it will just tell them that the address works and you will only get alot more e-mail from them.

It seems as if the Yahoo techs may be performing upgrades currently.  I'm having a different problem with composing email at this time (ie: there's no active area block to type the message in).  The last time this happened, the techs were upgrading the system, but didn't have the courtesy to send out an alert email indicating the system would be down.  It appears that some people never learn from their previous mistakes.

the address your sending to is not a valid address anymore, has it been awhile since you sent this person emails?
