Strange sendmail behaviour after upgrade to 9.1-BETA2

[Pavel Timofeev]

Hello everyone!
I've just upgraded (binary) my server from FreeBSD 9.1-RELEASE amd64
to 9.2-BETA2.
And my sendmail can't resolv any hostname. It says:
Jul 30 17:28:54 reticulum sm-mta[3191]: r6UCqeun016122:
to=<ptimofeev at xxx.ru>, ctladdr=<mox at reticulum.xxx.ru> (1001/1001),
delay=00:36:14, xdelay=00:00:00, mailer=esmtp, pri=300348,
relay=kalmar.xxx.ru., dsn=4.0.0, stat=Deferred: Name server:
kalmar.xxx.ru.: host name lookup failure

Meanwhile, I didn't change anything in resolv.conf and I can't find
anything wrong when I use nslookup manually. It works. Furthermore,
when I set to mailertable something like
xxx.ru                  smtp:[192.168.62.209]
where ip address is address of another server (not kalmar's which is
mx server) sendmail works but with strange log message
Jul 30 17:44:17 octans sm-mta[11666]: r6UDiGhD011656:
to=<ptimofeev at xxx.ru>, ctladdr=<mox at octans.xxx.ru> (1001/1001),
delay=00:00:01, xdelay=00:00:01, mailer=smtp, pri=30340,
relay=[192.168.62.209] [192.168.62.209], dsn=2.0.0, stat=Sent
(r6UDiG8v018961 Message accepted for delivery)
Why it says relay's ip address two time in log?
Is someone experiencing such problems? I mean can someone confirm
similar behaviour?
Could you please check on 9.2-BETA2 stuff like "echo bla | mail
myemail at mydomain.com"?
I can provide more info that you want. Thanks!
