Now, the answer begets a question: Is it possible that in a futureversion of Pegasus it could be an option for content filtering to use
the address book as a whitelist? I can see the logic behind both yes
and no answers, but an option would allow the user to choose. Any
thoughts?
I have no idea if this is possible at all and v5.x is going to have a new addressbook as well. Might be possible, but only David can tell if this will work out.
Subquestion (possibly answered elsewhere in the forums): is an update
to address book functionality (basically, bringing it in line with
current standards, it is dated after all) on the table?
There is going to be a new addressbook, probably based on one of the RFCs for an addressbook so it could be more easily imported and exported. David has done some preliminary work on this but we've not seen it.
