I am receiving a lot of SPAM mails from hinet.net domain to my mail server.
The mails are targetted to yahoo.co.tw. I am not sure why my mail server is receiving it.
When I checked the postfix logs there is no source IP address from where the mails are being sent from.
How this happens. Any one has similar experience.
Any idea how to block these.
