By default, due to nature of SPAM, you do not want to send error packet when SPAM packet is dropped as sending error back will:
- increase traffic on a server (which in rare cases may lead to overload of a XMPP server)
- notify spammer that it was not possible to delivery message
It is possible to configure spam-filter to send error back, by setting true to spam-filter return-error property:
Allow sending error.
'sess-man () {
'spam-filter' () {
return-error = true
}
}
