I agree with the idea (after all, the only *real* authority on what happens is
sendmail doing "normal" execution:-). In particular, just feeding destinations
through set 0 isn't nearly enough, since I've found that it is often the
*sender* addresses that get mangled beyond comprehension... However, I prefer
this method - IMHO it's simpler, shows *everything* that happens, and your UA
doesn't get in the way (must be run as a "trusted" user, of course):

/usr/lib/sendmail -odi -d21.x -f'env_sender' 'env_recipient' < 'letter'

where 'letter' contains at least

From: 'head_sender'
To: 'head_recipient'

and, of course, all the 'env_sender' etc are replaced by the addresses that you
really want to test. I find that x=2 tells the essentials of what's happening,
increase it as needed; I believe x=19 is the worst you can get... The drawback
with all this is, of course, that the letter actually gets sent if possible,
i.e. be careful with how you choose the addresses (at least the env_ ones).
