Handling UUCP Locally
Hosts sometimes deliver mail to a few UUCP connections locally and forward to other UUCP connections through a knowledgeable host. The rules that handle this situation often make use of another class:
R $* <@ $=V . UUCP> $#uucp $@ $2 $: $1 user@localuucp R $* <@ $+ . UUCP> $#esmtp $@ $Y $: $1<@ $2 . UUCP> kick upstairs
Here, the class $=V
contains a list of local UUCP connections. They are
matched by the first rule, which selects the
uucp delivery
agent. All other UUCP addresses are passed to the
knowledgeable host in $Y ($Y on
page 852). The user part ($:) that is given to the knowledgeable
host is the original address as it appeared to the
LHS.
