Want to hire - Postfix blacklist manager

Looking for someone to create a plugin to manage a postfix email blacklist.

- View, add and delete entries in a file (maybe delete all function also)
- On save, run 2 commands
-- "postmap /etc/postfix/blacklist"
--"postfix reload"

Entries can be IP, IP range, host or email address:
192.168.1.123
192.168.0.0/16
mail.spam.tld
jerk@spam.tld

File formatted like this:
192.168.1.123   REJECT   SPAM BLOCKED
192.168.0.0/16   REJECT   SPAM BLOCKED
mail.spam.tld   REJECT   SPAM BLOCKED
jerk@spam.tld   REJECT   SPAM BLOCKED

Let me know your thoughts

It's completely doable.  However, you could also use SQL for the blacklist, much like the rest of CWP uses.  Something to consider.
