Update: I resubmitted a unblock request with this post, AT&T has confirmed that they will remove the block. It was quick! Thanks!
AT&T blocked all emails sent from one of my servers, which I’m sure was a mistake, because the server hosts several forums and only sends notification emails to registered members, e.g., when a member asked a question on accessforums.net, if someone replied to his question, the forum will send a notification email. To be on the safe side, I have never sent out a single newsletter from these forums.
According to email server log, I submitted unblock requests here two times in the last two months, but no actions, no response whatever, just like a black hole. I’m sure they didn’t look into the problem at all, because anyone who read the emails or checked my server will know it’s a clean server.
Can anyone bring this post to AT&T admin’s attention? Your simple block has brought lots of inconvenience to our forum members (your customers).

Finally, AOL unblocked my new IP, their Feedback Loop Request Form doesn’t seem to work, I joined two times and was approved too, but nothing happened. The unblock was done after I got a personal reply to my direct email request.

On some websites, I really don’t want to use free email address for contact, but spam email is an endless war. Google App allows me to use my own domain as email address, I can also enjoy all the power and features of Gmail, and it’s free! What a perfect solution! If you are hosting your own email server and not satisfied with it, I strongly suggest you to give Google App a shot. Read More

Postfix has been running on my servers for a few months, but I haven’t been able to make SMTP Auth work, as a result, I can’t send emails from my desktop. Finally I decided to finish the configuration by following the tutorial on postfix.org. But unfortunately, it didn’t work after the first try. Then, a simple idea came out: why not try other SMTP servers instead of configuring mine? The SMTP server (exim) on my VPS relays any outbound emails after authentication. Read More
