Exchange 2010 Power shell script Guru

I am looking for someone who has expert understanding about exchange 2010 and power shell scripting. I am looking for a script to delete any secondary emails other than , @xxx.co.org. This script will get user details form a txt file. I have got a script which is picking up those email ids but not deleting, I am more keen to share that script with you. Either you write a one or make some changes to get it work.
