[IMail Forum] BLOCK NULL SENDERS

[copacs]

LS, Below you can see an email received from a null sender. We have disabled this but we still get these messages processed by the server. Also we have mail reley disabled. In this case a null sender from IP206.81.82.53:25 is sending mail to an other domain than ours. Can I solve this issue?
