Hi Dan,
I have now just extensively played around with it (again) adding and removing members, changing their user groups and such. It now seems to work. If my client has received the emails I cannot tell right now because it’s in the middle of the night here. I’ll ask them tomorrow.
Has the Member using the info@ address opted out by chance?
Urm, I tried to find something about opting out of EE but haven’t found anything and have never heard of it before. Where would one do this?
Have they checked spam/junk mail folders and filters?
They have told that they did but since I don’t have access to their mail server you can never know.
Thanks and Cheers!
Marc
Edit: I just thought about one other factor. The email address that never gets delivered is the same as entered in “Return email address for auto-generated emails” under Admin > Email Configuration.
