[Mimedefang] mimedefang 3.3, filter_sender and md_dkim_verify()

[Ralph Hayon]

Hi Dianne,

Ok, I could not find any documentation that states this. This was my 
guess based on my observations.

I am trying to easily get the domain extracted by DKIM to validate the 
sender's email domain.

I want to have a system that confirms that emails to my employees from 
other employees are valid and not faked.

Any suggestions how I can easily extract the arguments provided to 
filter_sender() in a filter function after filter_begin() so that I can 
use DKIM tests to assist with this?

Thank you for the information!

Thanks.

Ralph
