XCON: MTA Is Leaking During Content Conversion

After you configure an X.400 connector as shown below to disallow MS Exchange Contents to an Exchange Server site, and you send several messages out this X.400 connector, you may see a small but noticeable memory leak. This memory leak is logged just before content conversion is done.

X.400 Connector Configuration

On the Advanced tab, click X.400 Link Options, and clear the Allow MS Exchange Contents check box.
