See, I submit an request, to this request i get response through mail. I had Used CDONTS for mailing and as usual IIS 5.0. when ever user submits a request, the mails were sent to the user if that user comes under our intranet, if the user submits any external mail ids then the mails are Queued in Queue folder. for this purpose i had configured one more exchange server, which is our main excghange server through which external mailing problem was resolved. Now whats happing is if an intranet user submits a request, he is getting 2 mails & not one. so what should i must do to slove this problem
