Description Need Real Name 2001-08-16 21:08:09 UTC 
Description of Problem:

Under RH7.1 sendmail is checking /etc/hosts.allow to determine whether or
not to accept incoming connections, even though it "shouldn't" since this
isn't an xinetd-based service. Unfortunately the documentation doesn't seem
to mention this at all.

This can be fixed just by adding some notes to the docs that indicate that
a line should be added to hosts.allow for the service named "sendmail",
otherwise following the usual syntax.

If users set up a hosts.allow file without this line it can lead to an
overall failure of the sendmail system and dropped messages.

Version-Release number of selected component (if applicable):
sendmail-8.11.2-14 under RH7.1

/etc/hosts.allow and /etc/hosts.deny have nothing to do with xinetd. They are
used by the tcp_wrappers library (libwrap).

By default, RH7.1 does not deny access via hosts.deny. But you are right, this
should have been documented in the RELEASE-NOTES and not just in the sendmail
rpm changelog.
