Yahoo Email Issues - just me?

[Syneryder]

Another one of those "happening for everyone or just me" posts :) My emails to Yahoo seem to be blocked lately - they're coming back as "Deferred" and redirecting me here:

http://help.yahoo.com/l/us/yahoo/mail/postmaster/postmaster-22.html

The error code I'm getting is 4.16.50, which I've heard is grey-listing. Despite the deferred message, they appear never to reach the recipient. Any idea if that's a Yahoo issue, or is it just me?

Ironically, the latest time it happened was via a Yahoo Groups email list I participate on, and came back from some member I've never seen participate on the group... maybe an overzealous list subscriber is flagging people as spam?

Not just you.
Although some of the links below are several months to a year or so old, the situation remains much the same:

Ahh cool - I thought I had already searched the forums, but clearly I wasn't using the right keywords! Oh well.

It seems Yahoo wants a list of all IP address that I use to send email from, and I imagine the email addresses wouldn't just be the mail server, but any IP I connect to the internet with? I have a dynamic connection at home, so there's no way I could list every IP address for them. Does that sound correct, or am I confused?
