See http://www.ussg.iu.edu/usail/mail/debugging/ for more on debugging 
sendmail. You're unlikely to find a definitive list of sendmail debugging 
flags without looking in the source code because there are so many of them 
(around 200) and they change quite often.

Yes, I think Postfix has "policy daemons" you can write to set up whatever 
checks you want (equivalent to sendmail's milters I think). I know SPF checks 
can be done using a few tens of lines of perl in this way (see 
http://spf.pobox.com/postfix-policyd.txt).
