Hi

I have setup of 3 mail servers for domain. Netware with mercury is MX 10
and two unix hosts are MX 20. Now I want to do some spamcontrol. I set
up mercury to allow mail only from my two unix MX 20 hosts and refuse
the rest of the world.

The problem is: Some mail servers do not understand the 520 error
mercury generates and mail is NOT delivered from these domains.

I wanted to ask if this is legal configuration. And why mercury uses 520
error for that reason ? Has it been taken from some RFC ?

TIA

L.
