I'm trying to configure spam blocker. Unfortunetly when sending mail from my home network (tcpnet.pl) and trying to get access to my mail server I get message.
Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means.
I know that my provider is very well known as a spam sender, But I just want to use my mail server to send messages. Spam blocker catch all incoming messages to my mail server at port 25 ( include messages that have to be relaied at mail server) and dropped messages when came from my home provider.
How can I reconfigure spam blocker to accept message with defined senders even if senders network is blacklisted.
(sorry for my english, hope you understand what i was trying to descript.)
