there are some servers sending smtp emails through the exchange 2007 server
by open relay.
how can i set? they are at same single domain.
there is already default domain in accepted domain, but emails not go at the
following error
"#< #5.7.1 smtp;550 5.7.1 Unable to relay> #SMTP#"
when i set "*" at accepted domain, then emails sent but open relay to all.
grateful for assistance. thx.
