Docomo — MESSAGE

Hi,
I'm Having a problem sending msgs to ANY DOCOMO NUMBERS.
I'm able to to send msgs to other numbers n receive delivery reports instantly EXCEPT for ANY DOCOMO NUMBERS.
Some times they get delivered,bt still the delivery report doesnt comes!
Its definitely not the case of inbox being full, also he is able to receive msgs from other docomo numbers.
