It has been well known that Yah00 loves playing the 4xx games when it comes to accepting mails from outside their network. Within their network they allow unrestricted YoYo playing. When they are caught with the tricks they play they switch to dreaded permanently defer games. This is akin to Nazism on web.
How to deal with this issue when their postmaster address seems to be some outsourced joint in some jungle where the staff is only taught copy and paste of same crap again and again no matter how diligent you tend to be while trying to resolve the issue. Well, short and sweet answer is do unto them what they do unto you. Block their entire network with a 550 response if you administer your own server and place a nice message
"Contact Yahoo Customer Support To Resolve Failure Or Stop Using Yahoo"
Having done that would give you following stats after having run for a day (presuming your server logs the details)
(1) Number of times mail from Yahoo is rejected.
(2) Number of mails that you have in queue that are stuck because of 4XX Yah00 Games.
Equipped with this data then establish contact with Yah00 postmaster and tell the guy very openly that you are blocking entire yahoo network and give all the data to show that traffic indeed is not high as they will always claim.
This will also hurt PaidBizmail Yahoo users and they would also start troubling Yahoo Support. They definitely cannot be irresponsible to them as they are paying. Sooner or later the BOFH Admins of Yahoo will wake up.
Imagine if 1000 admins across the world do this and presuming each server rejects 1000 mails/day from Yahoo network. That's 1 million mails blocked. That will definitely cause the bosses to wake up from hangover. If they don;t listen, let them stay blocked. Then their PaidBizmail users will start ditching them.
There is no other way of dealing with this 4XX Yahoo menace. Their so called "Good Mailing Practise" is a load of S***.
If all admins start doing this it's end of Yah00 Mail for sure. Their admins will then perhaps defy RFC standards and start rejecting 550 responses also. Who knows!!!!
