Don't apologize, many people use lpd as an alternative to the hidden
complexity of CUPS.

Looking at the source (usr.sbin/lpr/lpd/printjob.c), it does not appear 
there is any option.  The sendmail() routine in that file could be 
modified.  Or if you filter outgoing mail at or before the MTA, that 
filter could be changed to look for mail from lpd and adjust the domain.
