smtp destination address rewrite

Hello, I would need some help in an irule for smtp connection that will search a phone number in the body of the email and would replace the destination addresses with that phone number plus the mail domain (eq 090232121@sms.sms.com).

 

The format in the body is this:

 

api_id:[API+ID]

 

user:[USERNAME]

 

password:[PASSWORD]

 

to:090232121

 

text:Hello test,

 

text:Your account details:

 

text:Username: xxxxxx

 

text:Password: xxxxx

 

The goal is to use an email to sms service in my organisation. The things i want to do is to delete the api_id,user,password and to put the "to" field in the mail recepient address.

 

Any suggestions?
