I'm not sure about the exact Sendmail configuration options you will need, but in general the following is important to keep in mind. To minimize DKIM signature corruption, it is important to sign at the final step before delivery of the mail to a remote SMTP server. This is true for both mail that is to be signed and originates locally (via a web application or a command line script), as well as for mail you receive via SMTP which you have to sign before delivering it to its destination (e.g. the Internet). Having said that, you will want to look for a Sendmail configuration that allows you to invoke the milter right before (or from within) the _outbound_ SMTP connection. You may have to define the milter in your ClientPortOptions setting, I'm not sure. Or switch to Postfix ;-) BTW: I wonder whether you implemented DKIM signing using the dkim-milter milter software or using OpenDKIM? As you post your question on the dkim-milter-discuss list I suppose the former is true. I'd recommend to forget about dkim-milter and start using openDKIM (http://www.opendkim.org/) as dkim-milter is no longer maintained and it's author dropped dkim-milter development and continued the dkim-milter work as the opendkim project.
