I have a proliant ml series server and i would like to setup up event notifier so when anything goes wrong, I will get notified. But I don't have mail server running in the network. and it seems the isp required to authenticate before to relay though their server. But there is no option to put username and password there. So I was thinking to setup smtp server in iis, I set it up, the emails went though first time, but after that it seems the recipient server blocked it..... so how can I make it? or if there other better way to achieve what I want to do?
