I have set up qmailtoaster as a gateway for exchange. my smtproutes contain this: thedomain.com:mail.exchange.com
and my rcpthosts contain: thedomain The problem I am facing now is, the exchange was able to send mails through me alright. But when mails come in, qmailtoaster is suppose to forward the mails to the exchange server but it is not, rather the mails are sitting in the toaster's queue. what else am I suppose to do? Thank you!
