that mail would fail. To help with translating registered BITNET names into Internet
addresses, John Gardiner Myers has supplied the bitdomain program in the contrib
subdirectory. It produces output in the form:
ucbicsi icsi.berkeley.edu
that can be put into database form for use with the K configuration command.
FEATURE(bitdomain) causes rules to be included in the configuration file that perform the
necessary translation:
R$* < @ $+ .BITNET > $* $: $1 < @ $(bitdomain $2 $: $2.BITNET $) > $3
Note that this rule requires BITNET addresses to be so identified with a .BITNET suffix. If
the address, without the suffix, is found in the bitdomain database, the Internet equivalent
address is used in its place. See also the UUCPSMTP mc configuration macro and
FEATURE(domaintable).
The form of FEATURE(bitdomain) is:
FEATURE(`bitdomain??)
This declaration causes the following K configuration command to be included in addition
to the aforementioned rule:
Kbitdomain hash /etc/mail/bitdomain
FEATURE(bitdomain) is one of those that can take an argument to specify a different form of,
or name for, the database:
FEATURE(`bitdomain??,`dbm -o /opt/sendmail/bitdomain??)
The extra argument causes the aforementioned K command to be replaced withth e
following one:
Kbitdomain dbm -o /opt/sendmail/bitdomain
The earlier bitdomain setting is safe.
