4.9. THE ADDRESS MAPPING TABLE
43
• Sendmail—CanIt-PRO will invoke the Sendmail program like this:
sendmail -OForwardPath=/dev/null -bv [email protected]
If the address resolves as “deliverable” to a single local mailbox, that mailbox name is used as
the stream name.
• Database—CanIt-PRO will look up a stream mapping in the Address Mapping Table (Section 4.9).
• AsIs—CanIt-PRO converts an address to a stream by removing any angle-brackets and converting letters to lower-case.
• ChopDomain—CanIt-PRO converts an address to a stream simply by chopping off the
@domain.tld part, removing any angle-brackets, and converting to lower-case.
• ChopUser—CanIt-PRO converts an address to a stream simply by chopping off the address@
part, leaving just the domain (without angle-brackets and converted to lower-case.)
• Program—CanIt-PRO converts an address to a stream by executing the account-info program. Please see Section 6.2.4 on page 74 for more details. Note that Program is deprecated;
you should create and use a User Lookup method instead.
• None—CanIt-PRO removes the domain from the Domain Mapping Table.
• If you have added external User Lookup methods (Chapter 6), some of them may appear as
additional choices. For example, the LDAP and Program User Lookup methods can convert
an address to a stream.

To modify the mapping for an existing domain, select a new mapping in the Mapping column and
click Submit Changes.
The special domain * is used as a last resort if the actual domain is not found. You may enter a
mapping for * to set a default mapping. If there is no * entry and a domain is not found in the Domain
Mapping Table, then CanIt-PRO uses a default lookup method of Database.
If you enter a string in the “Filter:” box, then CanIt-PRO limits the display to entries whose Domain
or Mapping columns contain that string.

The Address Mapping Table
CanIt-PRO uses an Address Mapping Table (Figure 2.4 on page 23) to map e-mail addresses to
streams. The Address Mapping Table is used both for hand-entered entries placed there by the CanItPRO administrator, and for caching the results of the Sendmail and Program mapping methods.
These methods are potentially slow, so caching their results can improve performance.
To edit the address mapping table, click on “Setup” and then “Address Mappings”. The Address
Mappings page will appear:
