resomta-a2p-647974 Sending error
Hello,
I am needing assistance with getting this error resolved. This is the same exact issue as this post: https://forums.xfinity.com/conversations/email/421-resomtah1p028516syscomcastnet-excessive-failed-authentication-esmtp-server-temporarily-not-avai/6581ba29e4ada5345193b7c1
We have had our IT look at this and the xfinity/comcast servers are blocking me from sending from my email at the office. I have verified that all devices that have this email attached do not have invalid credentials. This started happening a month ago. Is there a way Xfinity can whitelist my public IP at the office?
