Public bug reported: Binary package hint: postfix
I have a particular Postfix relay configuration where I need to forward SMTP to an SSH tunnel, and configure a relayhost_maps (sender_dependent actually) as [localhost]:12345. This worked in maverick, but fails in natty. The new Postfix 2.8 release strips RES_DEFNAMES from _res.options (the resolver flags) by default, which triggers a resolver bug reported separately as Launchpad Bug #777855. Note that this is not a Postfix bug, but a bug in eglibc - I am filing this as Postfix bug to document the issue and for possible workarounds should an eglibc resolution not be viable. A possible workaround, but dangerous, is to tweak Postfix's resolver flags as in http://marc.info/?l=postfix-users&m=130459442830727&w=2 by setting smtp_dns_resolver_options=res_defnames, but that causes false resolver results for some. Please see the entire thread at http://marc.info/?t=130456164100002&r=1&w=2 for a discussion.
