Can iRule change SMTP subject?

Can iRule Do this scenario?

 

I have SMTP traffic passing through F5 and I want to change Subject of some SMTP packet.

 

example. If mail subject is "Test" or mail come from IP "1.1.1.1". then iRule write subject "alpha" append to the old subject >> subject will become "Test alpha" .

 

I know we can customize HTTP payload but Not sure if it is SMTP header or SMTP payload. Thank you very much

    i think it could be done by stream profile/stream irule.

    Please see if this is valid or not

    when CLIENT_DATA {

    STREAM::disable
STREAM::expression {@test@testnaja@}
STREAM::enable

    }
