Hi @jphilbey ,
Welcome to the community!
We're sad to know that you're having issues sending email. We did an article that will guide you a basic troubleshooting on how to rectify this, please see link below.
Let us know how it will go.
I was able to confirm with our Postmaster that the ban has been lifted and it should be now working.
Let us know should you require further assistance.
Hi again Shane
No, as per the other day changing password does nothing.
Please unblock my email account.
We're glad to know that in case you'll have queries in the future do not hesitate to create a new thread here in our community.
Can send emails again, hope this stays this time.
