CAUSE

This issue may occur if hackers use your Exchange server to relay unsolicited e-mail messages (spam). As a result, the Badmail folder fills up with messages that your server cannot handle. The messages cannot be sent back, because the return addresses are not valid (spoofed).

RESOLUTION

To resolve this issue, follow these steps:
  1. Stop the SMTP service. To do so, follow these steps:
    1. In Computer Management, double-click the Services and Applications branch, and then click Services.
    2. In the right pane, right-click Simple Mail Transport Protocol (SMTP), and then click Stop on the shortcut menu.
  2. Delete all messages from the Badmail folder. By default, the Badmail folder is located in the Exchsrvr\Mailroot\vsi 1 folder.
  3. Start Exchange System Manager, locate the server that you suspect is being used to relay the junk e-mail, and then double-click Protocols.
  4. Double-click the SMTP node, right-click the virtual SMTP server, and then click Properties.
  5. Configure Exchange Server so that it relays only SMTP mail that originates from your network and from other trusted computers. To do this, follow these steps:
    1. Click the Access tab, and then click Relay.
    2. Click to select the Allow all computers which successfully authenticate to relay, regardless of the list above check box. This option makes it possible for SMTP mail from your internal network to be relayed through the virtual server.
    3. Click to select the Only the list below check box. The list that follows is frequently left empty, except in situations when you want to allow computers external to your network to be able to relay SMTP mail through the server. If you do want to allow computers external to your network to be able to relay SMTP mail through the server, click Add, and then configure the correct IP, IP range, or domain name.
    4. In the Relay Restrictions dialog box, click OK.
  6. To mount databases, follow these steps:
    1. Double-click each Storage Group under your server.
    2. Right-click the Store that is dismounted, and then click Mount Store on the shortcut menu.
  7. Start the SMTP service.
