While we have not heard from AOL yet, in recent experiments all email from AOL got through. However, these experiments were on a very small scale, so may not accurately reflect reality.
Domains hosted by Realtime appear to be back up again after being down for about five days. That email backlog has been cleared.
Email to the iwayafrica.com domain appears to be having problems. There isn’t much of this backlogged on the mail servers, but there is some. Same with a couple of domains hosted by Coppernet.
If you’re trying to communicate with people with unreliable email, why not refer them to NinerNet? We pay referral fees!
