detach command

Ok so I added event CLIENT_ACCEPTED disable one I found a pice of data. But each time I find the data and the if statement is triggered it does a TCP::release and event CLIENT_ACCEPTED disable. But then I see the client_accepted is again run. Any help would be great. Thanks

when CLIENT_ACCEPTED {
   set tcpdata ""
   TCP::respond "220\r\n"
   TCP::collect
   log "CLIENT_ACCEPTED"
}
when CLIENT_DATA {
   append tcpdata [TCP::payload]
   log "$tcpdata"
   switch -glob $tcpdata {
   "*DATA*"  {
         if {$tcpdata contains "Sensitivity: Company-Confidential\r\n" } {
            event CLIENT_ACCEPTED disable
            TCP::release
            TCP::close
            pool mailhost1v
            log "encript"
         }
         else {
            TCP::respond "354 Start mail input; end with .\r\n"
              log "ready for DATA"
         }
      }
   default {
         TCP::respond "250 OK\r\n"
      }
   }
}
