editer le fichier plugins
vim /etc/qpsmtpd/plugins
ajouter
dkimsign selector=alecto domains=bittwiddlers.com,bitnerd.com keyfile=/etc/ssl/certs/dkim-alecto.private
enfin ajouter votre champs au DNS
alecto._domainkey IN TXT "k=rsa; p=<key text>; t=y"
t=y pour que le destinataire ignore la signature
t=s pour que le destinataire la prenne en compte
il faut aussi ajouter une ligne sans selecteur The sending domain policy is published using a DNS TXT record as follows:
_domainkey.example.com. IN TXT "t=y; o=~"
The t=y value pair means that the example.com domain is testing DomainKeys.
The o tag denotes the outbound signing policy. ~ (tilde) means that the example.com domain may sign some emails with DomainKeys. - mean all emails are signed
Additional fields for test (t), responsible e-mail address (r), and notes (n) may also be included - for example "o=-; n=some notes".
note pour domainkey t=n pour ne pas etre en test, mais t=y est pour test aussi
