Hi All,
First of all mail server must be configured properly to work everything smoothly, such as hostname and other virtual domains etc must exists in the /etc/hosts file. Most Importantly RDNS must exist for all the domains. If all the domain share single ip address then all domain must be entered in the /etc/hosts file against that ip address. Example: 1.2.3.1 mail.vanaz.com mail.bbc.com mail.cnn.com Secondly, the key that all the domain get signed by the DKIM for all the domain is the singconf.xml file. Example given below: The default signconf.xml file contains the first section in brown color below with a domain=”/var/qmail/control/me” in it. Remove this line and add query="dns". Coz of this the dkim looks for the hostname or domains in the “/var/qmail/control/me” file to sign the mails for. Add your domains individually as shown in the example below. <dkimsign> <!-- per default sign all mails using dkim --> <global algorithm="rsa-sha1" domain="/var/qmail/control/me" keyfile="/var/qmail/control/dkim/global.key" method="simple" selector="dkim1"> <types id="dkim" /> </global> After modification your signconf.xml file should look like as in example given below, and if everything is set accordingly then everything should work: <dkimsign> <!-- per default sign all mails using dkim --> <global algorithm="rsa-sha1" query="dns" keyfile="/var/qmail/control/dkim/global.key" method="simple" selector="dkim1"> <types id="dkim" /> <types id="domainkey" method="nofws" /> </global> <vanaz.com selector="dkim1"> <types id="dkim" /> <types id="domainkey" method="nofws" /> </vanaz.com> <bbc.com selector="dkim1"> <types id="dkim" /> <types id="domainkey" method="nofws" /> </bbc.com> <cnn.com selector="dkim1"> <types id="dkim" /> <types id="domainkey" method="nofws" /> </cnn.com> </dkimsign> Regards, Anil Aliyan From: Rob Wellard [mailto:r...@brainiacmedia.net] Sent: Wednesday, April 14, 2010 12:56 PM To: qmailtoaster-list@qmailtoaster.com Subject: RE: [qmailtoaster] domainkeys mulitple domain issue I Guess nobody knows the answer, if i work it out, ill let you know.

However i seem to be getting a weird problem with the domainkey. I have several domains on the one toaster, and i can get the last one working perfectly, however the rest come back with bad signature. And it’s always the latest one that seems to work. Is there something i am doing wrong. Please can you help
