smtp.comcast.net rejecting login credentials
For some reason smtp.comcast.net is suddenly rejecting our login credentials, preventing us from sending e-mails. This problem is occurring across all of our devices including Windows 10 computers and iOS iPhones and iPads. We haven't changed anything on our side. We've used the same login credentials for a year and have been Xfinity customers for nearly 10 years.
Incoming e-mail (from a 3rd-party server) and all other Internet features working fine.
Spent a hour on the phone with two different Xfinity tech support people, but no solution. Now we have to wait for a call back from some other Xfinity support.
Both my wife and I work from home and suddenly losing our e-mail capability is huge deal. Anybody else?
