Configuration 59
LDAP Mailing List Exclusion Rules
You can exclude particular addresses from being treated as mailing lists.
If you have any entries in your directory server that match a mail list rule, but
should not be treated as a mailing list, list them here. This might include:
• Internal mailing lists that do not have outside email addresses
• Printers, conference rooms, and other non-user resources
• Mailing lists that should be treated as individual users, with separate archives
and quarantines.
Exclusion rules are based on string values and regular expressions, not LDAP
settings.
This page shows the list of exclusion filters. In a new configuration, this will be an
empty list. To add exclusion filters, click the Add Exclusion Filter button at the
bottom of the screen.
On the list of exclusion filters, you can change existing filters as follows:
• Reorganize: Click the up arrow or down arrow icon to change the order of
exclusion filters.
• Edit: Click the notepad icon to edit the settings of an exclusion filter.
• Delete: Click the X icon to delete the exclusion filter.
