David,
I have no idea what you are talking about. This has nothing to do with
Yahoo.
Oh, but it does. It has everything to do with Yahoo Mail, and their decision to break almost every mailing list on the planet. AOL and a few others followed suit.
One of my people send a message to the group and his email is
modified like that.
That member must be using one of the accursed email services.
If I can stop it please let me know.
You can't, but the member could chose a less benighted email service.
That being said, I am I think signed up on this group as a daily
summary and I am getting all the messages one by one all day long.
Putting on my GMF owner hat, I can confirm that you have two subscriptions to this group, at two different email addresses. One that joined Jan 22nd and is set to Summary, and a second that joined early this am my time (10:43am UTC), and is set to Individual messages.
