You can overcome this issue by running a local forwarding DNS server locally on your network and use this as a DSN resolver for your network.

How will postfixadmin > generate the passwort to add mysql db. Postfixadmin is a mysql/pgsql frontend which is not a part of Postfix, not supported on this list. I think they have a web forum for user-to-user support. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

I really do appreciate. That's a nice way of saying you did not understand 99% of the reply. > Although I am getting a bit lost. Is it possible for different clients to > have the same IP address in such a short period of time as per my logs > posted? zen.spamhaus.org provides a service that depends the DNS client IP address. Low-volume DNS clients get free service, but high-volume DNS clients have to pay for a subscription. For example, if you use the resolver at a big ISP, or a public service like 8.8.8.8 or 4.4.4.4, then zen.spamhaus.org won't work well for you, if at all. Wietse

Unless you have the old config and log files, we can only make (likely false) assumptions, so it won't help here. Also, if that system is gone, you can't test assumptions by changing this or that. A dead end IMHO. > 2) On the current system, the main.cf content_filter configured for 10024 or > 10028 seems to be totally inert, Because mail gets caught by pickup before it has a chance to go through the content filter on port 10024. I don't know if this behavior can be changed (I'm thinking about filters vs milters ?). > not doing anything at all for mail received > from the outside. It's only when I loop back to 10024 after the pickup > filter that messages are scanned. pickup comes very early in the pipe. These are handwritten notes I took when I was learning how e-mail works, it would be nice to have feedback on them ? http://imgur.com/a/Asyqr -- Yassine
