[EXIM] how can accept msg when its coming from ip

Hi folks,

    by defualt exim rejects mail if reverse-dns is not resolved for
the incoming ip rite?? (no/mismatch ptr record and so on....) 
eg
------------------------------------------------------------------------------
1997-12-03 16:08:27 connection from [207.155.118.xx] refused (reject host)
------------------------------------------------------------------------------

how can I disable checking reverse dns calls or something...

thanks
-Bikesh-
