sendmail problem in receiving

[ssrikant]

I am stuck with a sendmail problem.I am able to send to different users at different domains but not to users in my domain.i have modified my dns configuration files and i found my mails posted at /var/spool/mqueue irrespective of the users,all mails are posted in this folder.

can any one think of something which cud be wrong in my config files

when i do the telnet mydomain.com 25 and all the above stuff (post1)
when i enter :

rcpt to:<root@mail.mydomain.com>250.2.1.5

i get:

<root@mail.mydomain.com> .......recipient ok (will queue)
after completeing the restof the procedure

the message is being queue at /var/spool/mqueue (mandrake9.0)
once this is done when i flush the queue i get
the following

$sendmail -q -v

Running /var/spool/mqueue/h47Mnde2002461 (sequence 1 of 1)
mail.mydomain.com:Name sever timeout
<root@mail.mydomain.com>...transient parse error message queued for future delivery


i dont understand head and tail from this and iam tired and i have lost all hope of seeing my sever running any directions is highly appreciated

Sounds like it can't find the name server(DNS server)
mail.mydomain.com:Name sever timeout
