White list in MSM

Hi,

 

 

The customer would like to build their own white list, so I add the following iRule in the smtp virtual and set it as higher priority than the MSM one. Do you think it's a proper way or I have to integrate inside the MSM irule? Thanks in advance.

 

 

 

when CLIENT_ACCEPTED {

 

if { [matchclass [IP::client_addr] equals $::white_list] } {

 

pool good_mail

 

}

 

}

 

 

Regards,

 

Ken
