How do I correct failure notices including mailer-daemon@yahoo.c?
the mailer-daemon@yahoo.com will send you an email when yahoo cannot deliver the message to the desired recipient. a few reasons explain this:





1) wrong email address


2) the email address doesnt exist anymore (ie removed or deleted)


3) the server that collects the email for that address is down





if you are sure that the email address is correct (recheck just to make sure) then the problem is most likely on the recipients end
Reply:could be server is too busy or sometimes you just enter the email adress wrong.
Reply:your saying it goes through at times.could be their mailbox is full or you cannot hit forward to send to that address.My daughters work is like that .I have to compose a new message every time.
