DKIM does not sign on Vertualmin 4.0

After upgrading from virtualmin from 3.99 to 4.0 I am having a problem with signing DKIM signature. And all emails are queued for aprrox. 5 min for incoming delivery.
I’m using Centos6.3 but also tried with debian6 and results are same.

Any tips are appreciated.


Are you seeing any errors in the email logs, in /var/log/maillog, when trying to send a message that should be DKIM signed?


Eric, thank you for your response.

Here is what I got when I sent out email.

There is a unusual delays.

I Appreciate your help.

May be Vertualmin 4.0 has problem with signing DKIM and smtp process. So I rolled back to 3.99 from backup image.
I will wait for next release and hope it will be fixed.
