Name
FEATURE(nouucp)
Synopsis
If your site wants nothing to do
with UUCP addresses, you can set the nouucp
feature. Among the changes this causes are that the
! character is not recognized as a separator
between hostnames, and all the macros that relate to UUCP (Section 4.6) are ignored. This feature truly means
no UUCP.
You declare nouucp like this:
FEATURE(`nouucp') ← through V8.9 FEATURE(`nouucp',`nospecial') ← V8.10 and above FEATURE(`nouucp',`reject')← V8.10 and above
Beginning with V8.10 an argument has been added that can either be
nospecial or reject. The
nospecial causes sendmail to
simply ignore the ! character. The
reject causes sendmail to
reject mail with the ! character. If you declare
neither argument (as in the first line), and you are using
sendmail V8.10 or above, you will see the
following error, and your configuration file will fail to build
properly:
*** ERROR: missing argument for FEATURE(nouucp):
use `reject' or `nospecial'. See cf/README.Note that all the other UUCP declarations (such as UUCP_RELAY) will
be ignored if you use this nouucp.
When you use this feature on any machine that forwards
uucp mail to a central mail hub machine, be
certain that you also declare it on that mail hub machine. If you
don’t take this precaution, you open up your mail
hub to risk of unintended relaying.
