Hello,
Yesterday, a local user was infected by a virus, and it start sending
thousands (100.000 aprox) of spam mails (it converted in a sort of
open-relay). Each mail only include 4 or 5 recipients.
My qmail-toaster accepted them, becouse the user was using smtp-auth,
and the user didn´t violate my chkusers policies.
How can I control such behaviour?
There isn't really way to control this. If they're flooding the system
you could use a firewall rule to block them if they send mroe than x
number of emails in a 60 second span, but ultimately they will still
have the virus and need to be cleaned.
