Some Mailman list subscriptions delayed (resolved)
We recently upgraded Mailman to fix a problem for Yahoo and AOL users, which has worked well.
Today we found a problem where since the initial upgrade on April 24, people who tried subscribing to a Mailman list by sending an e-mail message (instead of using the more common Web interface) weren’t properly added to the list.
This was caused by an incompatibility between our mail system and one of the Mailman software changes. We didn’t receive a report of this problem until today because few people try to subscribe this way.
We’ve resolved this: Any delayed subscriptions have been correctly handled and the incompatibility has been fixed. We apologize to anyone affected by it.
