Hi Bill, Thank you so much for your help. Apparently it's related to issue #1 you mentioned. The server could not find the blacklist server, and this is still due to the earthquake's damage of lines in Asia.
It also could not find zen.spamhaus.org Oh well, nevertheless I cleared out the blacklist and now connections are restored. Thank you again for the prompt help. If you ever come by Guangzhou, China, drop me an email and I'll invite you to dinner :-) Best regards, Peter Wu On 1/18/07, Bill Kwok <[EMAIL PROTECTED]> wrote:
Hi Peter, 1. Please check if your /var/qmail/control/blacklists contains any obsolete servers and make sure they can respond to you wihtin a resonable time. You can also minimize your blacklist. Currently, I have only one entry: -r zen.spamhaus.org 2. If you connect to the email server by using your ISP's dynamic IP, make sure it is not blacklisted. If that's the problem you are facing, you may consider creating the submission port (port 587) for authenticated users to send email. I suppose the stable version should have already had such feature built-in (Would anybody correct me if I am wrong).
