qmail's problem

[info]

Hi everybody I have a problem I've set up qmail-1.03 and all the others packages, webmail,vpopmail,signup, autoresponders,etc... all working fine form domain.com Now i have few others domains... domain1.com which can send and receive e-mail internally, for the network 192.... I can also send e-mail outside of the 192 net, but i CANNOT receive any e-mail from the outside world, these for each virtual domain i try to set up Any idea? would be very appreciate. The main domain.com works fine also from the outside I'm going nuts.....  Thank you in advance
