Hi there! Our aministrator mailbox is overcast with thousands of notifications about captured or infected mails, which we don´t sent (in SMTP log are IP addresses wich are not equals with senders domain = I think senders address is generated by virus or spam engine). Is there any ability in Exchange 2000 how to configure verifications of senders domain? (and consequently ignore that mails) Or is this problem resolving by 3th party products? Thank for any response.
