That is sendmail deciding it had not heard from the milter before one of the
set timeouts in your milter definition (in your sendmial.mc file) expired.

So at this point sendmail temp failed the message.

Looks like MD was almost done with it at this point too if it was appending
boiler-plate text... does it actually end up being delivered? (I suspect not
once MD gets notice from sendmail it was temp failed or it was passed back to
sendmial then dropped since it was tempfailed already, not sure which scenario
but something like that).

Tweaking your sendmail.mc file for your timeouts might help. See:
