can no longer receive email from a particular address topic locked?
For some reason the thread I recently posted is locked (shows a padlock and no way to reply), so I am answering a posters question here.
The domain is gmail.com.
thanks to both posters for their helpful replies.
he just started hearing from his subscribers that they were not receiving them
Also ask him to "scrub his unsubs". Some people will mark a email as spam if they unsubscribe but still receive the emails. I think what Cox might have changed is how many "mark as spam" until the sender(either their IP or domain) is blocked.
If the sender didn't get a bounce back, see if they can the email headers(to another non Cox email) of the email they sent to the Cox email address. If I can compare those headers to the ones for the test email I sent, then maybe I can see what the root problem is.
PS. You aren't the only one having this issue, I just haven't see what the problem is clearly documented.
