# Anti-Spam-Bait Recipe summary:
|
| 35 |
# Obviously somebody has been paying attention. The spam baiting check
|
| 36 |
# is now sufficiently complicated to warrent an external program for
|
| 37 |
# testing. It is defined in SPAMBAITTEST. If it returns a non-zero exit
|
| 38 |
# code, addresses are mangled a la _nospam.
