Are you using mailertable?? Then, be sure to put the hostnames/ipaddressess
between [ and ] brackets... Otherwise sendmail will perform another MX lookup
through DNS and will give you this error...

For Example:

[root at bb ~]# cat /etc/mail/mailertable
domain.tld         esmtp:[]
domain2.tld        esmtp:[mail.domain2.tld]

Good luck
