I have a few emails being forwarded for different domains. If I set the forwarded email address to something like hotmail, it goes through, but ISPs and other servers are blocking it. What would be the reason for this? example If I sent this directly from outlook, I never get a message back from my server saying the message could not be sent. I'm looking more through the logs and see a lot of blocked for abuse messages. These are just basic messages, so something coming from my server these other mail servers don't like. Edit: I've also seen some errors "DNS Check Error"
Make sure that the hostname of your server exists in DNS and that the IP of your server is a static IP and that you have a correct reverse dns record for your IP pointing to the hostname of your server.
For some reason I can see Reverse DNS was no longer set up. My provider is adding the entry for me, I'll see if that fixes it.
Now I see I'm getting blocked for abuse from Att Looking at the att.net/blocks page it seems to think I am spamming. Why would this be and how can I fix it? Reverse DNS is now working and resolving to my hostname.
That's the form I filled out to get a response. I sent an email back but no further response yet. I sent them the error notice right from my logs which clearly shows that I'm being blocked for abuse, but they say they don't see it. Doesn't make any sense. I did get through to another server that was giving me problems before, so at least part of the problem is fixed.
