Hi Murray,

Thanks for the response. I did do a google search before posting. Most of the resources were about the libmiter package and developing milters using the milter API. I was interested in the actual communication between the MTA and a milter. Only related page I could find was, 
http://cpansearch.perl.org/src/AVAR/Sendmail-PMilter-0.98/doc/milter-protocol.txt

However, as I mentioned earlier, the response commands such as 's', 'i' are not documented in this page. 

The wikipedia page (http://en.wikipedia.org/wiki/Milter) does mentions that "documentation of the protocol used for communication between sendmail and milter processes is not provided. This internal protocol is subject to changes in new sendmail versions." Probably the responses I am receiving are introduced in later sendmail versions.

Any other relavent documentation you are aware of will be helpful.

Thanks,
Elan.

A Google search for "milter protocol" produced some highly useful results.

You might also look at the "miltertest" tool in the OpenDKIM package.  It provides a scripting interface to do what you're after.

Subject: [dkim-milter-discuss] dkim-milter protocol documentation

Hi,

I am trying to write a script that would directly communicate to the dkim-filter process through its socket using the milter protocol. My script would essentially act like sendmail. In the process I am finding some responses whose meaning I am not aware of. For example I get responses with command 's', 'i' which don't seem to be documented as a part of milter protocol. Is there a place where I can find the meaning of these response commands from dkim-milter?

Thanks,
Elan.
