We've had reports that some users with Gmail accounts have not been
receiving Groups mail since approximately March 14, 2007. This was a
difficult issue to diagnose, because we were able to replicate the
issue with some, but not all, of our test Gmail accounts. Some of us
were missing Groups messages in our Gmail accounts, some of us were
receiving them as usual. We appreciate those of you who wrote in
detail about the problems your members were having on the Groups
Technical Issues board and in email to Customer Care. Having detailed
information helps us get to the bottom of issues faster.
The problem appears to be on Gmail's end. We have gotten in touch with
the Gmail team and are working to resolve this issue. We'll post an
update when this has been resolved.
We've posted further information about email delivery on the Yahoo!
Groups Team Blog: http://blog.360.yahoo.com/y_groups_team?p=3094
