freebsd stable - Dec 2014 - 10.1-RELEASE-p3 possibly broke parts of dns resolution in postfix

Hi,

it appears that update to 10.1-RELEASE-p3 broke my mysql maps in
postfix, where hosts is specified with FQDN. Changing it to IP address
works around it.

This worked, but does not work anymore:
> pacija at mail:~ % sudo cat
/usr/local/etc/postfix/smtpd_sender_login_maps.cf
> user = someuser
> password = somepass
> hosts = host.example.org
> dbname = somedatabase
> query = SELECT goto FROM alias WHERE address = '%s' AND active = 1
With conf like this I see the following message in
maillog:
> Dec 25 16:47:15 mail postfix/submission/smtpd[1885]: warning: connect to
mysql server host.example.org: Unknown MySQL server host
'host.example.org' (0)
This works:

/usr/local/etc/postfix/smtpd_sender_login_maps.cf
> user = someuser
> password = somepass
> hosts = 192.168.1.10

Also, when submitting mail to submission port, it does not resolve
recipient domains, so mail is being rejected when
reject_non_fqdn_recipient and reject_unknown_recipient_domain are on.

Both forward and reverse drill are resolving fine.

-p3 didn't contain any changes to DNS lookups
-p2 however did include a fix to unbound.

Its still very unlikely that either of these caused a breakage as we 
would have had a flurry of reports before now if there was an issue.

Given this I would recommend you check for an unrelated issue, possibly 
configuration else where?
