Hi,
We have been getting an error message when sending emails to all members. Attached the error message:
Emails to the the following members were skipped
for the reasons listed below:

Stephen Buckhout
CC,ALB (invalid/non-working email address)

Do you have any idea how to fix the issue? Thanks a lot

Thanks a lot for your help. Jin

Stephen's email should work now. He hosts his email in a data center that frequently spams FTH. and the email server IP was blocked. This could happen again.

Hi Brian, Thanks a lot.
I will share the information with Stephen. At least, it is working for him now. Cheers
Jin
