I have an issue with Yahoo blocking email sent from a new server I have. All my other servers are fine, have no idea why Yahoo do this now. I am working on it.
But they are being held in the queue, and there is no bounce back to the sender to let them know. Is this normal?
Its just I sent an email to a customer several times and he kept calling me to say he didn’t get it, and I was asking to double check his spam etc. Turns out it was me, being held in the queue. Its a permanent failure, so I should have been told.
The error from Yahoo is:
host mx-eu.mail.am0.yahoodns.net[188.125.69.79] said: 421 4.7.1 [TS03] All messages from xx.xx.xx.xx will be permanently deferred; Retrying will NOT succeed. See http://postmaster.yahoo.com/421-ts03.html (in reply to MAIL FROM command)
Hi,
It appears your email is being “permanently deferred”. Because the messages aren’t being rejected by Yahoo! they won’t bounce. However, Yahoo! appears to be adding your messages to a permanent deferral queue which is pretty much the same as rejecting your message meaning they won’t be delivered to the end user.
Honestly, getting off a block list can be a pain, though not impossible.
Here are some details on Yahoo! and some steps to get off their blacklist.

I’ve tried all I can, and although it says it could take a couple of days (too long for me) other people online have stated it took weeks.
In fact, this server is a Digital Ocean server and there are a couple of posts on the Digital Ocean forum by people wondering of Yahoo are blocking Digital Ocean. None of my other servers were blocked, only this new one by Digital Ocean.
So I decided to get a new Linode server, and moved all my email accounts to that, and not use the Digital Ocean one. The emails sent right away even though the new Linode server would be the same as the new Digital Ocean. So the Linode IP was not blocked.
Digital Ocean are low cost, which is why I went for them for an Email server, half the price as Linode, but if we get issues like this its not worth it. I had two DO servers, going to merge them to one Linode so it costs the same now.
Hi,
IP address blocks are the way most providers block inbound traffic when it comes to spam and other complaints. There is a process for getting off a block list, and yes it can take time depending on the issue which caused it.
Any service provider who recycles IP’s between customers (basically every provider) can have anyone or more of their IP’s blocked. This really isn’t provider specific, but rather an issue with the way users make use of IP addresses. Sometimes these are innocent mistakes, and other times it’s intentional.
Either way, don’t think that simply switching is going to permanently solve the problem. It might be a good idea to ensure that you are complying with all the email rules just in case you unintentionally contributed to the block. This way you don’t find yourself being block in the future for something you din’t realize was a cause.
Trust me, even we’ve experienced blocks in the past, most of which were easy enough to resolve, but annoying just the same. Often times a provider will block you over a false positive which really sucks, however it’s always good to know what triggers a block with a specific provider.
