Hi, I have Postfix configured to query some maps (proxy:pgsql) on my Postgresql-server which is only accessible through IPv6. Occasionally I see following errors:
postfix/smtp: warning: connect to pgsql server db.domain.tld: could not translate host name "db.domain.tld" to address: hostname nor servname provided, or not known? The hosts is defined with IPv6 address in /etc/hosts FreeBSD getent can (currently) not be used to resolve hosts to IPv6 (http://www.freebsd.org/cgi/query-pr.cgi?pr=161548). dig fails to resolve unless I request the AAAA-record. I've tried putting the IPv6-address in as host (both 2001:xxx:xxx:xxx as well as [2001:xxx:xxx:xxx]) but that doesn't work either. What is the correct format I can put in proxy-maps? Any idea why hostname resolving seems to work most of the time but sometimes fail? N.
