Hi, This question may be showing my ignorance about the basic functioning of mail or dns as much as of exim; if so, and you know a better place to ask, please point me there. I can''t find the answer in the FAQ. I have a single computer handling several domains each with a real IP address. This works fine for web sites, and for receiving mail. It also works for sending mail, except that a reverse dns lookup of the ''from'' ip address does not necessarily match the domain in the reply-to address, causing my outgoing emails to be rejected as spam by many systems. How do I get the ''from'' ip address of my outgoing mail to match the domain in the reply-to field? (I am using IMAP with thunderbird as client and my outgoing smtp server set as my ISP) Thanks for any advice Graham

I suspect that there is something else broken in your system. Can you send a test message to mh+pkg-exim4-users at zugschlus.de so that I can see what might be broken there? Spam filters that force the reverse DNS of the delivering server to be identical to the sender address would not accept any messages from most (if not all) large web hosters, and I doubt that they are in wide use.

Talk your isp into opening port 25 for you and letting you run your own nameserver Then you could include a subnet file that would fix reverse lookups. bob On Tue, Dec 04, 2007 at 09:36:49AM +0000, graham wrote:> Hi, > > This question may be showing my ignorance about the basic functioning of > mail or dns as much as of exim; if so, and you know a better place to > ask, please point me there.
