DKIM appears to not include such headers (but no personal 
experience here): «DKIM attaches a new domain name identifier 
to a message and uses cryptographic techniques to validate 
authorization for its presence.  The identifier is independent 
of any other identifier in the message, such in the author's 
From: field.» http://www.dkim.org/

Mutt-wise, would it be doable to set user-defined variables to 
specific patterns (e.g., my_f1=~p!~f…) and expand them to 
limit the view (i.e., use variables as shortcuts for complex 
match patterns)?  This is a question since I am not so 
mutt-proficient as I'd wish to be… :-)
