Command detection

Newcomers to mailing lists will sometimes send the command "unsubscribe" to the mailing list posting address, rather than trying to follow the unsubscribe directions. Also, some automated email programs, such as "vacation" programs, send messages in response to anything they receive. If someone is on vacation, there is a risk that this vacation message could be posted to the mailing list.

For these reasons, Lyris List Manager automatically detects a wide variety of list manager commands, such as "unsubscribe" and "on vacation" and intercepts them before they make it to the mailing list. These built-in filters are successful in the vast majority of cases. If a new case occurs (perhaps some new, foreign language vacation program is released), you can augment the built-in command detection with your own Action Phrases.
