Hello all,
I have been fighting a problem with yahoo in that they are deferring all of my mail. Of course I have gone and filled out all of their forms and such but I just cannot seem to figure out what is going on and they for sure are not getting back to me. Anyways I think I have narrowed it down to be that it is a domain keys problem and that is why they are blocking me. Does anyone have any kind of an idea as to what I can do to start to get my emails flowing back to them? Thanks for your help Q Here is the error messages I keep getting: Connected to 216.39.53.1 but greeting failed. Remote host said: 421 Message from (74.218.24.5) temporarily deferred - 4.16.50. : Connected to 216.39.53.1 but greeting failed. Remote host said: 421 Message from (74.218.24.5) temporarily deferred - 4.16.50. ly deferred" or "421 Message from x.x.x.x temporarily deferred" errors when sending mail to Yahoo!? If you are seeing the error code "421 Message from x.x.x.x temporarily deferred" or "451 Message temporarily deferred" in your SMTP logs, this indicates that the message you attempted to send was not accepted at Yahoo!. It is not a permanent error; your system will automatically re-try later.

If you are not the administrator of the mail server in question, please contact the administrator directly with the error message you are receiving.
