Not sure if this is even possible. We have a customer who was send/receiving emails just fine last night. They are on a home network with Xfinity. Today the customer was unable to send/receive emails. I was able to remote into their PC and verify their Outlook settings. I tried browsing to WebMail but that failed. I tried pinging the server and that failed. It worked fine from their cell phone using DATA but on Wifi it failed. We rebooted their Xfinity wifi router/modem but that didn't help.
Is it possible for cPanel to block/blacklist an IP Address out of the blue? I'm assuming this is probably an Xfinity issue but thought I'd ask while I'm in the middle of troubleshooting this issue for the customer.
