Comment 0 for bug 1068036

on a (freshly installed) system with nis authentication, postfix is no longer able to read aliases from the nis table mail.aliases.
in 10.04 it worked

symptoms are:
- errors in /var/log/mail.log:
warning: nis:mail.aliases is unavailable. unsupported dictionary type: nis
- and mail is not forwarded

Obviously some build switch was changed between 10.04 and 12.04.
In 10.04:
$ postconf -m | grep nis
nis

In 12.04 the output is empty.

But still in 12.04 the postfix.postinst skript looks for nis and creates an appropriate mail.cf entry for lookup in nis:mail.aliases
