Yahoo (AT&T and a couple of other providers are using their infrastructure) apparently has changed an outgoing spam-filtering rules and is now blocking messages with a specific formatting of the "Reply-to:" header.

Go into Tools > Account Settings (or right-click on the account in question in the folder list to the left of the main window, then select "Properties" from the menu) and go into the main tab of the account. There is a "Reply-to address:" field which can be used to direct responses to your message to a different address than the one of your account. If you don't need that feature, just clear that field and click the Ok button. Now your message should go through.

That's an excuse that you don't have to accept, it only means that they won't help you setting up Thunderbird, etc. It's a server problem on their end and they can fix it by reversing the spam-filter rule which is causing the trouble. This has happened before with Yahoo in another instance, also related to their spam-filtering, thus apparently they haven't learned from that case.

Confirming based on number of reports seen in the forums.

THANK YOU.

I knew it was not something at my end since it worked fine the day before.

THIS definitely worked.

I remember getting caught the last time they changed settings as well. 2003/2004 I think it was.

Again, THANK YOU.

Respectfully,

You are welcome. Hopefully Yahoo will address the issue if they get enough complaints, I'll keep this bug open for tracking.

There have been forum reports that affected users filled in their old Reply-to address again and it didn't get refused by the Yahoo server any more. Thus, maybe they silently removed that rule again.

Can someone verify and/or check with Yahoo if that's the case? Thanks.
