Yahoo has reported some connectivity issues with some of their MX's
« on: April 13, 2011, 01:08:37 PM »
Hello,

Yahoo has confirmed that they are currently experiencing connectivity issues with some of their MXes.

Yahoo is returning 420 Resources unavailable temporarily. Please try later (mta1255.mail.ac4.yahoo.com)) codes.


Thanks

I just saw the same error on one IP (high volume), my guess is, it is either yahoo issue or a way to rate limit.

Hello,

"420 Resources unavailable temporarily. Please try later (mta1047.mail.mud.yahoo.com)"

We believe, the error above possibly rate limit of undocumented of Yahoo! errors.

Anyone experience this?

Thanks

I am seeing this error with only one IP, and have begun to think this is rate limit, not server issues at yahoo. Interestingly, I don't get back off notification for yahoo, Maybe I should check my config first.
