Description Charles Gillet 2006-08-31 17:42:56 UTC

Description of problem:

/etc/hosts ignored for resolving aliases (hosts: files dns in nsswitch) after
upgrade to U4

Version-Release number of selected component (if applicable):
 
postfix-2.2.10-1.RHEL4.2

How reproducible: consistently


Steps to Reproduce:
1. Use base postfix setup
2. put an alias that points to another mail gateway for delivery
/etc/aliases:
test:  test.net

3. if gateway is only in /etc/hosts (not in DNS) postfix will bounce message as
undeliverable because it can't resolve the name
  
Actual results:

bounces message as undeliverable - unable to resolve host address

Expected results:

should look in /etc/hosts, resolve from that file, and send the message to the
remote system

Do I need to open a case with Redhat support to get an acknowledgement here? 
This change of behavior broke things on a production server.

Comment 2 Thomas Woerner 2006-09-25 12:50:41 UTC

Please set "smtp_host_loopup = native". THis should solve your problem.

Comment 3 Thomas Woerner 2006-09-25 12:51:27 UTC

smtp_host_lookup = native

Comment 4 Charles Gillet 2006-09-25 15:53:05 UTC

"smtp_host_lookup = native" does fix it.  Thanks!

Comment 5 Thomas Woerner 2006-09-25 16:03:55 UTC

Closing as "NOT A BUG".
