Some
sites have a number of workstations that never receive mail directly.
They are usually clustered around a single mail server. Normally, all
clients in a cluster like this send their mail as though the mail is
from the server, and they relay all mail through that server rather
than sending directly. If you have such a configuration, use a
declaration such as the following:
FEATURE(`nullclient', `host.domain')
Note that the host.domain must be the fully
qualified domain name of your mail server or relay to the outside
world.
If you wish to prevent the nullclient version of
sendmail from trying to access
aliases, add this line to your
mc file:
undefine(`ALIAS_FILE')
Note that this works only with V8.8 and above .mc
files.
