Hi all,

exchange server . But I receive messages that are not forwarded to me; seems
sth. like relaying .

Any ideas?


Our exchange server : ntsrv.bisod.com.tr (

The internet headers of two example msg.s I received:

1. Unknown email address and no To field message have received

Dear all,

I have using Exchange 5.5 with sp2 on a NT4 machine.

Some time I found some email messages, which is addressed to other (not in
our exchange server) or no information in To field, in my Inbox.

Is this symptom caused by the exchange server setting?
Any suggestion to solve this problem?
