Re: [mailop] What is Yahoo TSS09 ?
It appears that Farhad Hedayatifard via mailop said: >I had this happen with a new IP block a couple of weeks ago as well. We're all set. Whenever Yahoo sees mail from a block that's never been announced before they assume that it's probably an abandoned block that's been hijacked so they block it. I can't blame them. Once I told them, no it's just me and my user Bob, they fixed it and I can see the mail queues are draining.

Re: [mailop] What is Yahoo TSS09 ?
I had this happen with a new IP block a couple of weeks ago as well. Sign up for the Yahoo! Complaint Feedback Loop on https://senders.yahooinc.com/ and then contact them about your specific problem using this form https://senders.yahooinc.com/contact/. I guess you can skip the CFL registration, but from what I've heard having registered for it will improve your reputation with Yahoo! They asked a few questions and fixed the problem for my IP block in 3-4 days.

Re: [mailop] What is Yahoo TSS09 ?
I am moving my servers to new IP addresses, which is always fun. The new block is 192.55.226/24 which was allocated in 1989 and has never been live until this week. So here's what AOL says to innocuous messagee from my users. 553 5.7.2 [TSS09] All messages from 192.55.226.66 will be permanently deferred; Retrying will NOT succeed. I presume it has something to do with it being a hitherto unseen IP range The volume is quite low, maybe 200 messages a day including from my mailing lists, and does not look spammy. The highest volume list is gossip about folk dancing. Any suggestions? To answer the obvious questions, it all has DKIM signatures and the SPF is updated, so it ain't that.
