It's not the notifications setting. The fact is, that when my Synology NAS sends a push notification to my cox email, I do NOT get the emails. I have verified this by adding both my Cox email address and my business email address to my Synology, then sent a test message. I get the one to my business address immediately, but nothing to my Cox email. I have done this multiple times, with my Mac email both open and closed. When my Mac email was completely closed, I logged into my cox email through my browser, and there was nothing in my Inbox or Spam folder. I have turned off all all spam settings as well. All of my other (non synology) Cox emails I receive with no problem, that I know of. I have also used another Cox email address, and still nothing. I do not get the emails on my phone or ipad as well.
The Synology push notification settings are fine, and I can verify that because I get the emails to my business account. However when I input a cox email address, I do NOT get the notifications!
I'm not trying to be a jerk here, but I have a degree in Computer Science. I'm not your "average" home user. I wouldn't have started this thread if I didn't think there was something at Cox blocking synology push notifications. I have also troubleshot everything on my end.
