SMTP Email Problem on Alert Manager

teguhprasetio93

I've found a problem when testing out the alert manager on Solarwind Orion NPM

the error message is:

EXCEPTION STACK: --> Failure sending mail. : System :

at System.Net.Mail.SmtpClient.Send(MailMessage message)

at AlertingEngine.SolarWinds.SWActions.ActionEmail.AsyncMailToSend.SendThis(Object state);;;

Unable to connect to the remote server : System :

at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout)

at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback)

at System.Net.PooledStream.Activate(

Any help is appreciated

The error would indicate that the Orion systems cannot connect to the SMTP server you are specifying. A couple of things I would make sure:

1 - if you have AV on the server, make sure mail filtering is not enabled (NPM emails can be seen as spam from an unknown third party by mail filtering)

2 - if the SMTP server is exchange, make sure the exchange server is setup to allow connections from the NPM server.

3 - try the ip address of the SMTP server rather than the name.

Thank you mharvey for your kind answer

I just recently found the problem, the internal network is protected by the proxy. The problem is I don't know how to by pass the proxy on the Alert Manager

can you give your solution?

thanks in advance

I'm guessing the NPM server isn't inside the internal network? You should be able to make an exception for the IP of that server in order to get it to talk to the exchange server.

the server is certainly is inside the internal network, the problem is I don't have enough authority to change the permission to make an exception on the proxy.

Well, I will solve this somehow

Thanks for the help
