Sorry to revive an older thread but I am trying to come up with a basic 
SPF policy.  I have added TXT   "v=spf1 a -all" to my dns.  Since we 
use webmail, it seems fairly safe and hopefully effective to keep folks 
from spamming with our domain names.  Does this make sense or does 
anyone have suggestions for improvement or keeping us from shooting 
ourselves in the foot?

Now, i want to set keywords in bofh and the option in courierd am 
confusing myself completely.  Could someone with more experience 
suggest an initial setting to reduce spam but hopefully little valid 
mail?

Thanks for any suggestions,
