SYMPTOMS
After you configure an e-mail disclaimer in Microsoft Antigen 9.0 for Exchange, Exchange cannot deliver e-mail messages to certain domains. E-mail messages remain queued for delivery to the destination domains. When you troubleshoot this issue, you notice that the affected destination domains reject the SMTP connection from Exchange.



CAUSE
This issue occurs if you have internal messaging servers that do not use the MIME format for e-mail messages. When Antigen appends a disclaimer to outgoing e-mail messages that are not in MIME format, Antigen may leave a bare line feed (LF) after the disclaimer. Therefore, the e-mail messages are in a non-standard Internet e-mail format. Certain destination e-mail servers may reject these messages.



RESOLUTION
To resolve this issue, follow these steps:
 * 1) Start the Antigen Administrator program.
 * 2) In Shuttle Navigator, click Settings, and then click General Options.
 * 3) Under the Scanning heading in the General Options pane, click to select the Fix Bare CR or LF in Mime Headers check box, and then click Save.
