Hello, I experienced a strange problem with sendmail on FreeBSD 6.1 which happened during a routing problem on a network which isolated my network from the outside. On five out of seven boxes my logs started to show (capital names used to hide real ones) : Aug 30 15:53:13 MYHOST sm-mta[6247]: l7UAqbOp091438: to=USER@MYDOMAIN, delay=03:00:00, xdelay=00:00:00, mailer=esmtp, pri=618410, relay=MYMAILER.MYDOMAIN., dsn=4.0.0, stat=Deferred: Name server: MYMAILER.MYDOMAIN.: host name lookup failure Running an MX query with nslookup on MYHOST was correctly giving MYDOMAIN mail exchanger = 1 MYMAILER.MYDOMAIN. and 'host MYMAILER.MYDOMAIN' was correctly resolving the name. The problem did not show up on two boxes. All boxes run 6.1 and have default sendmail configurations. The only difference that I can see is that the two unaffected boxes run dhclient while the affected ones have static IP but I don't how it could affect the issue. Any idea what could explain this? Regards, Thierry.
