I have seen various threads about email authentication or the ability to use a DNS entry instead of the IP address, which neither Dude currently supports AFAIK. But you can use a notification type of “execute on server” with blat.exe, a command line mail client, to get the above options in a Windows environment.
The following is a notification type of “execute on server” I have setup on a 2003 server:
blat -body “[Device.Name] ([Device.FirstAddress]) [Probe.Name] service is [Service.Status] ([Service.ProblemDescription])” -to xxx@yyy.com -s “[Device.Name] ([Device.FirstAddress]) [Probe.Name] service is [Service.Status]”
Replace the xxx@yyy.com with the recepient email address. The body is the quoted text after -body and the subject line is the text after -s.
You can find blat.exe at http://www.blat.net
If you need even more flexibility (such as getting the date and time inside the message), you can probably create a batch file and manipulate the body or subject strings before sending them to BLAT and execute the batch file as a notification.
I just found The Dude. What a Great Tool!
