yahoo n hotmail not accepting mail from one domain

[sylvan dacounha]

Dear ALL,
   
  I dont know really if my problem is DNS problem or MTA problem
   
   
  i have a redhat server 9 as my primary name server running the following
   
  bind-9.2.1-9
  sendmail-8.12.5-7
  domain name = kmun.gov.kw
  ip address = xx.xx.xx.1
  mx record for kmun.gov.kw= xx.xx.xx.1
   
  this server also host another domain baladia.gov.kw
   
  i also have a secondary DNS running
   
  bind-9.2.1-9
  ip address = xx.xx.xx.2
   
  all has been running perfectly well for long time
   
  recently we decide to have a mail server for our other domain 
   
  baladia.gov.kw
   
  installed sendmail (same version )on our secondary DNS server that is
  xx.xx.xx.2 and set up a mx record
   
  xx.xx.xx.2
   
  and everythin is working fine..
  i can send send mails from my new domain that is baladia.gov.kw and also all mail send to any user at baladia.gov.kw is received perfectly OK
   
  but i have found that whenever i send mail to yahoo or hotmail the mail gets delivered to junk mail folder and not to inbox
  but mails sent from my earlier domain kmun.gov.kw are delivered correctly to the inbox
   
  both domain configs are the same n the zone files are correct and sendmail is configured likewise
   
  aslo i have checked if the servers are in spam n infact they r not
   
  so jus wondering why mails sent from my kmun.gov.kw get delivered to yahoo and hotmail correctly and blaladia.gov.kw do NOT.
   
   
  really appreciate you help
   
   
  Thanks and regards
