It's been a significant revelation, for me, to realize how common it is for DKIM 
processing to occur during the SMTP session.

So SMTP issues reduce to finding ways of preventing the cross-net transfer of 
data or even of preventing the SMTP session.  Oddly, I think the latter is more 
feasible than the former.
