Hello everyone-
We had an incident where a trusted connection from Microsoft had a
nice large dump of spam - it appears that several of their customers
were compromised.
"Trusted connection" is an obsolete concept. Has been for years, but
people hate giving it up. People can be trusted, computers not so much.
Filter all your mail. Never forward anything that your filters think is
spam or any other flavor of garbage. NO MAIL can be trusted based simply
on where it came from.
We've stopped it, and we're sure it's not going to happen again, but
yahoo has listed our IP address blocks with a dreaded "553 5.7.2
[TSS09] All messages from X.X.X.X will be permanently deferred;
Retrying will NOT succeed. See
https://postmaster.yahooinc.com/error-codes";
I've filed a help request at senders.yahooinc.com, but I'd love if
anyone has a contact at yahoo that could help.
I believe Lili Crowley has been helpful to people mentioning Yahoo/AOL
issues here. Her address should be in the archives...
In my experience, at least in recent years, Yahoo has the only
properly-working unblocking system among any of the behemoths. Not fast,
but functional.
We've got a lot of schools that have parents with yahoo email
addresses, and we really want to get things cleared up with them as
quickly as possible.
My least favorite mail stream ever was school progress reports. Students
are often motivated to report them as spam, which occasionally will
convince a mail provider to filter them. And many providers who don't
filter them will still send a steady stream of spam reports of them in
their FBLs and instill a sense of impending doom.
