To remove a email recipient using fwmailcfg in Brocade switch

Hi

Is there a way to remove a email recipient using fwmailcfg in Brocade.  i can see the options to disable,enable mail alert and to set the email recipient but not an option to remove few recipients. Also fabric watch allows to set email recipients for each and every class. I want to remove the recipient from all 12 classes in one go. Is that only it can be done in Webtools and not in CLI ?Appreciate your answer.
