    anyone ever seen something like this:

    Received: from p213.54.176.55.tisdip.tiscali.de (HELO ?192.168.122.254?) (213.54.176.55)

    seems these mail get blocked by aol cause 192.168.122.254 doesnt resolve

    The customer's computer is saying it is 192.168.x.x, but the real IP is 213.54.x.x.

    Why the 192.168.x.x IP is even in the headers is a good question. But I wouldn't relay mail that says its from 192.168.* or 10.* or 172.16.* either..

    Sorry, let me re-phrase:

    I host in the US, and all the emails which used to come into my hosted domains from tiscali.de were of a Spam nature, so I blocked them out.

    Luckily, none of my hosted clients (local businesses) have had need for much international emailing, so on most of my servers I am able to block out entire countries with no affect on my clients, other than reducing their received Spam emails...

    AOL will block mail if there is no reverse dns entry. If you don't control your PTR records contact your ISP and ask them to setup a reverse DNS entry.

    The computer that you are sending the email from, is it getting it's IP through DHCP? Do you have additional IP addresses so that you can you assign it an IP?

    seems i found my problem ...
    outgoing mail used to go over eth:0 = x.x.x.2 which has reverse dns.

    now i mail from foo.com which has x.x.x.17
    but the mail goes out of x.x.x.10 which belongs to foo.org and it eth:9 ???
    now wth is going on, i thought qmail binds to the first interface ???


    hehe :D knowing what to look for, i found an "old" post by art:
    qmail is annoying in that it will cycle through aliased IP's on your box. You can force outbound mail packets to be rewritten so they appear to come from a specific IP, using iptables:

    iptables -t nat -A POSTROUTING -o eth0 -p tcp --dport 25 -j SNAT --to-source <YOUR IP>

    any configurable way to fix qmail to an ip tho ??? and why didnt qmail seem to have done it in the last 2 years ?
