You should really fix your system resolver lib config. The subdomain name
should not be a TLD.

Normally, the $j macro is automatically defined to be your fully
qualified domain name (FQDN).  Sendmail does this by getting your
host name using gethostname and then calling gethostbyname on the
result.  For example, in some environments gethostname returns
only the root of the host name (such as "foo"); gethostbyname is
supposed to return the FQDN ("foo.bar.com").  In some (fairly rare)
cases, gethostbyname may fail to return the FQDN.  In this case
you MUST define confDOMAIN_NAME to be your fully qualified domain
name.  This is usually done using:
 
        Dmbar.com
        define(`confDOMAIN_NAME', `$w.$m')dnl

As I mentioned in my previous post, I overide the FQDN sendmail derives at
startup (the canonical name) by using the following in my sendmail.mc

define(`confDOMAIN_NAME', `mail.mydomain.com')dnl

Why don't you post a couple of lines from /var/log/maillog. Sounds like
sendmail may be looping to itself.
