Hi everyone,
We currently have a webhosting-environment with many websites. Those
websites is capable of sending email (obviously) via the local SMTP
function.
But sometimes, some of the websites is compromised and used to send
quite alot of spam from the websites - often using random domains.
So, one of the "solution" would be to implmement some kind of filter,
that check the SPF of the domains on outgoing emails and check if they
include or contain the IP or network of our environment and if not, the
emails is just discarded.
Ofcourse, we would employ more anti-spam features, but this would be
only one of them and could probably save us from blacklisting in some
cases.
Thankful for your answers!
