A certain forum I visit isn't sending out email to my email addresses which reside on my server. I have tried different emails from different domains on this server and neither work. I tried using my gmail account and I got the subscription emails. No other users of the forum are having this problem. The first week i signed up I was getting emails for replies, but then it all of the sudden stopped with no changes made to my email or board settings. I was still having instant email notification enabled and was subscribed to all the threads which I replied to. Would this be a problem with my server or theirs? I have found the ip of the domain and couldn't seem to find it being blocked by my server's firewall.
