I don't think that 1 and 2 are true; 1 is just a matter of codingstyle, and 2
is related to the sensitivity of it. Simply let people chose if they want 4, 3,
2, 1 or 0 octets to count...
I suggest that there should be a default setting of _2_ octects, which you can
change, and that you are able to add e-mailaddresses yourself using one of two
formats:
1. [EMAIL PROTECTED]
2. [EMAIL PROTECTED]:[1-4 octets]
Based on the numer of octets in 2 that is the sensitivity for that address; to
be able to change current whitelists to this model I suggest that
[EMAIL PROTECTED]:0 is used in cases where the IPaddress should be ignored.
NOTE: To be able to change the default setting without having to delete the
whitelist there must be a flag that will show if a listing is at a default or
"hardcoded" sensitivity.
