Qmail Anti Spoofing PatchThis patch might not be usefull for everyone but in some cases you want that some "from adresses" are only from a particular subnet or ipadress. It works a bit like badmailfrom. When a domain or emailadress is related with some subnets , using a from address from another subnet mail will be rejected by qmail-smtpd. An antispoofing control file looks like this:
As you can see domains or emailadresses and IP adresses are related. In this
case sombody using [EMAIL PROTECTED] has to come from 10.10.42/255.255.255.128. A
domain that is not mentioned will not be rejected. I have not tested it really good. But on my system the latest patch works. So if it does not work , don't be afraid to send me an email with your comments. If you have some ideas, don't hesitate to mail me about it. I will work on it as soon as I can or if you can let it work sooner, let me know. As I have not that many time, any help is always welcome. Thanks to Joerg Backschues for his contribution to the latest patch. jozzel at subweb dot cc |
