This is gold, I could set up my alias in no time!
However during the last few days, I’m having this error when sending some email messages:
“Your message couldn’t be delivered because the group you’re sending to needs to know who you are before it will accept your message.
To fix this problem, ask the email admin for the group to configure the group to accept messages from you.”
It seems to be when the recipient is Outlook.
Any idea what this might be?
