The opposite condition also occurs. Frequently, systems may have a number of
|
|
direct UUCP connections that are used infrequently or that are not as reliable
|
|
and always available as the default mailer or relay host.
|
|
<P>
|
|
For example, in the Seattle area there are a number of systems that exchange
|
|
the various distributions via anonymous UUCP when the distributions
|
|
are released. These systems talk UUCP only when necessary, so it is generally
|
|
faster and more reliable to send mail through multiple very reliable hops and
|
|
common (and always available) relay hosts.
|
|
<P>
|
|
It is easily possible to prevent UUCP delivery of mail to a host that you are
|
|
directly connected to. If the remote system has a fully-qualified domain name,
|
|
you can add an entry like this to the domaintable:
|
|
<P>
|
|
<P><P>
|
|
<P>
|
|
This will replace any occurrence of the UUCP name with the FQDN, and thus
|
|
prevent a match by the UUCPNODES line in the sendmail.m4 file.
|
|
The result is generally that mail will go via the RELAY_MAILER
|
|
and RELAY_HOST (or DEFAULT_MAILER).
