Hi Prak

You must create a Data Class(class_trusted_clients) and an iRule to filter which IP is allowed to access to SMTP server. Like this:

when CLIENT_ACCEPTED {
    if {![class match [IP::client_addr] equals class_trusted_clients]}
    { 
        drop
        log local0. "dropped: [IP::client_addr] is trying to access to SMTP"
}
