If you're sending a DSN, then the From: header could be your address,
but the MAIL FROM should probably be <>.
That prevents a lot of bad things from happening.

Setting the MAIL FROM to your address means that you could end up
challenging a non-existent address, then the mailer_daemon that
bounces the mail back to you.
If the C/R system was really broken, it could challenge bounces 
from a non-existent address endlessly, but in the normal case
this is only twice as much work as you need to do.
