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.

Howdy,

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.

thanks
