*scratch head* I don't know why you wouldn't allow use of a domain you
own... but if you don't want it used you should be able to add it to a
blacklist at the MTA level. On sendmail, add
photocraftlab.com REJECT
to /etc/mail/access, rebuild the access map, and off you go. You could
also DISCARD, or use any valid SMTP response code- "550 Mail for this
domain not accepted" for instance. No point in even *involving*
MIMEDefang, unless you want to do more specific filtering.
I don't know where to look on other MTAs, but something similar should
be possible.
