UUCPSMTP mc Macro
If your site has a host that used to be a UUCP site but is now on the network, you can intercept and rewrite the old address of that host into the new network address. For example, mail to the machine wash used to be addressed as wash!user. Now, however, wash is on the network, and the mail should be addressed as user@wash.dc.gov.
The UUCPSMTP mc macro provides the means to specify a UUCP-to-network translation for specific hosts. The earlier example would be declared like this:
LOCAL_RULE_3 UUCPSMTP(`wash',`wash.dc.gov')
The UUCPSMTP mc macro should be used only under LOCAL_RULE_3.
