Level: Warning
Keywords: Classic
User: N/A

Failed to get LegacyExchangeDN to build User Address Cache for the following SMTP addresses:@example.com; @exchange2010.local;
Conditions
1. Open the SMSMSE console.
2. Click on the Admin tab.
3. Click the Views|System Settings item.
4. The textbox List of internal domains contains domain names that are not internal.
A content filtering rule is configured with a user SMTP address condition. See the following article on how to set and check this: Specifying the users and groups to which the rule applies.
When a content filtering rule has a user condition with an SMTP address SMSMSE attempts to map that SMTP address to any legacy X.400 addresses configured for the user in Exchange (see the following article for details: Details About the user address caching feature of Symantec Mail Security for Microsoft Exchange (SMSMSE)).
SMSMSE issues LDAP calls to the domain controller for this information. If the LDAP call fails then these events are reported.
Remove any external domains from the list configured in SMSMSE.
