As administrator on some wiki email list, I received this morning the following message for each yahoo address on the mailing list This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: <user email>@yahoo.com SMTP error from remote mail server after initial connection: host f.mx.mail.yahoo.com [98.137.54.237]: 421 4.7.0 [TS01] Messages from 91.198.174.5 temporarily deferred due to user complaints - 4.16.55.1; see http://postmaster.yahoo.com/421-ts01.html: retry timeout exceede -These users subscription got disabled by mailman. -The actual MX host varies, sometimes it was f.mx.mail.yahoo.com, sometimes it was c.mx.mail.yahoo.com -91.198.174.5 is lists.wikimedia.org -Attached with the rejected message was an email sent with date 30 Aug 2009 (has yahoo been rejecting "temporarily" the emails since then??). -An better url would be http://help.yahoo.com/l/us/yahoo/mail/postmaster/errors/421-ts01.html "This error message indicates we are seeing unusual traffic from your IP address and/or that emails from your mail server are generating complaints from Yahoo! Mail users. Please note that this is a temporary error, and we encourage you to retry sending emails to our servers approximately 4 hours after you encounter this particular error. If you are seeing this error consistently over a 48-hour period, we encourage you to provide us with detailed information, including the complete error message you see in your logs, by filling out this form. (Note: Please make sure to select “Getting deferrals due to user complaints” in the form’s dropdown menu.)" Subscribers shouldn't be merking the list messages as spam. And in case a spike of emails sent from the lists triggered yahoo filters, they should refine them. I have notified my affected users and manually reenabled their subscription. Subscribers to other lists may not be so lucky.
Mark, can you take a peek? Thanks!
Just confirming - have received a couple dozen complaints about these issues from daily-article-l subscribers.
New Bounce notification batch, with several yahoo subscriptors disabled (but not all of them) because it tried too much times (4) to send to yahoo server emails dated 4 days ago, which were rejected with the above message.
Any status on this? I'm concerned given that approximately 3,000 (!) people have been unsubscribed from the daily-article-l mailing list as a result of this issue. Unfortunately, I have no record of the addresses (unless they email us separately - as dozens are doing). Is there any internal logging of these actions that a server admin might have? Either way, some resolution (soon) would be nice here.
Unsubscribed? They should appear in the subscriptors list, with a mark in the 'without mail' column. Don't remember the letter (reason) that it adds into bracket. You just traverse the subscriptor list unchecking them and sending. Beware, people may have disabled themselves mail delivery. Then the reason is different.
No - if the mail continues to bounce the list is unsubscribed (and removed from the list). I've talked to Mark on IRC about getting a list of those addresses and in the meantime I've disabled the automatic unsubscription.
Can this have been caused by users complaining about the emails coming from the default (forced) activation of emails being sent by the LiquidThread extension ? See Bug 21457 (whose severity should really be elevated to "critical", rather than current "normal").

No. I don't think liquidthreads was enabled at that time. Even now, it is only in some development wikis, it's not in any way widespread to cause this (and people testing it should know better...).

A few tens of notification e-mails a day on several low-traffic wikis? Give me a break.
This seems to have corrected itself through Yahoo. No action is needed here.
