Essentially you would have two INPUT_MAIL_FILTER lines that define the two filters (on different ports, of course), and then start those filters with different options as needed. In your double-signer example, one of them might show 127.0.0.1 as a "peer" so that SMTP connections from those sources are ignored entirely. > Although I'm learning sendmail, I'm by no means an expert.

The MDA you're using is not necessarily DKIM-aware, although free ones that are can be found (e.g. I think procmail has DKIM plugins). I think waiting for that feature request to be resolved might be the simpler solution, though it won't be available for a while. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
