update 2/5
From Yahoo
Our connectivity levels have been stable since Wednesday noon (PST). That said, we are still investigating reports of timeouts when trying to open a connection, as well as dropped connections during the DATA portion of the SMTP transaction.
update 1/27
It appears that once again Yahoo is having issues as they recently send out this message
Sorry for the late update, but as I'm sure most of the senders have noticed, we're again experiencing low connectivity on our MTAs, starting very early this morning.
We're working hard to restore the connectivity to normal levels, and I'll post an update as soon as I have some good news.
Please stay tuned
1/26
For those of you that might have seen some issues with delivery into Yahoo yesterday, those issues have officially been resolved. If you are still finding issues you may need to look into other reasons.
The official word from Yahoo yesterday was
If you're seeing some queuing in your outbounds today when sending to Y! users, we're currently experiencing low connectivity across our MTAs, which started this morning. We're working to get things back to normal.
The SMTP error message being generated by the issue should be:
"420 Resources unavailable temporarily. Please try later
Our apologies for the inconvenience.
