duplicate email

I've been receiving duplicate notifications for posts in the same group lately. It's not every message, but it is happening frequently. The messages have identical content, but the message IDs are different when I view source.

I've been dealing with a similar issue locally, so it was kind of nice to see it happening here. Has anyone else been receiving duplicate notifications from Groups.drupal.org?

Right now when a post is submitted to multiple groups and a user is signed up to those groups we get multiple email notifications with the same email. Is there any "easy" way to set it up so there is only one email notification per post and that it lists the groups that the post belongs to? It's not a huge deal but would help when going through emails. :-) Moshe and anyone else, any ideas on this? Is it possible and how much work would it be?

I searched and found a feature request here:

Thanks,
