I use dnn1.0 and smtp server(iis) in the same server. the dnn can send email at the beginning. but someday later, it stopped. and when i restart the server, all the mail in the queue are sent out, but still can not send email while normal running. also, i noticed a lots of bad mail in the badmail directory.
1. i want to konw how to setup smtp server in IIS ? if i disable anonymous login , is it ok?
2. is it possible that others use this server as relay and make it impossible to send out mail?
thanks,
Michael Jiang
