Package: postfix
Version: 2.11.3-1
Severity: normal
If I understand correctly, setting
smtp_host_lookup dns,native
should allow postfix to resolve hostnames from /etc/hosts if they are
not resolvable via DNS. However, this does not seem to work in practice:
[0] root@thinkpad:/etc/postfix# grep lookup main.cf
smtp_host_lookup = dns,native
[0] root@thinkpad:/etc/postfix# /usr/sbin/postfix reload
postfix/postfix-script: refreshing the Postfix mail system
[0] root@thinkpad:/etc/postfix# echo test | mailx nikol...@rath.org
