Email notifications not working

#1

I configured all the related email settings under Admin (Delivery Type: SMTP, SMTP Server/Username/Password)

From here I open System Health and select “Test Email Settings” and enter my own email. The system runs for a minute or so then spits out this error:

Error 1 of 4

Any suggestions on how I can correct this?

Thanks

Hi Pierre,

The error message means either there is no SMTP Service up and running and listening to the specified port 25 (52.34.221.85:25) or the email server is simply restricted from receiving any request from the server where Dundas BI is installed.

To verify, you can use telnet command from command prompt just to check if the port is open. This probably will not work and in that case, you might need to tweak firewall of the dundas server or email server to allow outbound or inbound requests respectively.

25 is the incorrect port - it should be 587. How do I change this? Ive looked through the settings under the “email” filter in config and cant find anything

Check out the following screenshot - it should help

Hey,

As the error says, this has something to do with certificate installed in either client (dundas server) or email server. This link has details: https://stackoverflow.com/questions/9983265/the-remote-certificate-is-invalid-according-to-the-validation-procedure
I believe you will need to ask your IT admin managing these servers. Let us know if you need any help further.
