| I'm using XMail on a QNAP NAS.
I want to set up authentication for all non-local domains. But I want to receive mail for local domains without authentication.
Right now it is "POP before SMTP". But that is no good because if I am logged in for POP anyone can send SMTP if they pretend I am the sender.
On my old server "POP before SMTP" meant they had to send from the same IP as the POP login.
How can I set this so no one can use it as a spam relay?

|So judging by the lack of replies, no one knows how to set up "POP before SMTP" in a way that spam is not relayed.|

|Pop before SMTP should use the IP address- are you sure you tested it correctly?|

| How could I have tested it wrong?
As long as I am logged in from POP3 anyone from any IP can send mail as long as they use my email address as the sender.
