Comments on Set Up DKIM For Multiple Domains On Postfix With dkim-milter 2.8.x (CentOS 5.3)

Set Up DKIM For Multiple Domains On Postfix With dkim-milter 2.8.x (CentOS 5.3) This tutorial shows how you can sign your email messages by using DKIM (DomainKeys Identified Mail) for multiple domains. Signing email allows the recipient of a message to confirm a message originated with the sender's domain and that the message content has not been altered.

Hi there,

It's really a very good tutorial. Steps were very easy to follow. I have couple questions for you. When I send email I get the following error in my maillog:

nov 17 21:27:37 mail2 dkim-filter[11742]: 9CA3CDAC64: no signature data

And when I send email to [email protected] and I get the following result:

DKIM Signature validation: not available
DKIM Author Domain Signing Practices: no DNS record for _adsp._domainkey.connect2b.net

Please can you help in this regard.

You can configure DKIM regardless of if you're using SPF. They don't affect one another at all.

I did exactly the same way asked to do.

But i could not make it work . I am using Zimbra on Debian 5.

Does it work for that kind of OS. Please let me know.

I don't get any error, but i don't get to validate a Domain key or DKIM verified.

 I used this source to test my email. Is there any specific port the email should go from ?

Hi,

I used this document to install and use dkim-milter with zimbra 6 collaboration suite on CentOS 5.3. After implementing DKIM I am unable to receive incoming mails whereas outgoing mails are going without any problem. Could anyone please tell me what may be the reason.

 Regards,

I have same problem, do anyone solve this problem. i have used Centos 5.5X86_64 and zimbra 6.0.7.  when i remove  milter_protocol = 2 DKIM does not work. but also if i put them to the file No mail will be recieved.

Everything works as a charm. I used rpm from the EPEL repository. Only had to modify the init script to use a port instead of a socket and tweak dkim-filter.conf a little bit.
 

Also added _adsp._domainkey     IN    TXT    "dkim=all" to my zonefile. Take a look at <url>http://en.wikipedia.org/wiki/Author_Domain_Signing_Practices</url>  for an explanation.

Thanks for a great guide.

You shouldn't modify the init script.  Instead put custom changes in the /etc/sysconfig/dkim-milter file so they will persist even after an rpm update.

smtpd_milters = inet:localhost:20209
