Error to send notification e-mails

Raquel Oliveira Nov 28, 2016 8:53 AM

Hi, guys!

I'm facing an issue while trying to get VizAlerts to send notification mails (even execution errors notifications).

The application is able to get the trusted tickets and process the view we are testing correctly, however it is unable to send mails. I get the following message while executing the app:

[ERROR] - send_email - Email failed to send; there was an issue sending mail via SMTP server: SMTP AUTH extension not supported by server.

Before raising this new discussion, I have researched through the community trying to find a solution, but even though some people have faced the same exception message as I'm facing, none of the solutions that worked for them has worked for me.

Also, I have checked and re-checked several times the SMTP data on VizAlerts' configuration file, and it is correct (also, it's the exactly same data used by Tableau Server, on which it works fine).

May you please help me with this problem? What could it be? Also, please tell me if any other information I may have not given right now is required to help to analyse this issue!

Thanks soooo much in advance!!

Gratefully,

Ana Raquel

Hi Ana. Thanks for doing your research first! Sorry that the other posts haven't helped you resolve. This error generally means that you should not be using a username or password in your SMTP settings, because the server doesn't support authentication. So these two settings should be as follows:

smtp.user: null
smtp.password: null

Are you already using those settings? If so, something else that is weird is going on.

Hi, Matt! Thanks for replying so fast!!

No, actually as the configuration on the Tableau Server wizard had user and password set for this SMTP server, I assumed it would be required on VizAlerts as well. I'll try setting the user and password as null and them run the process once more.

Regardless the outcome of this test, I'll post the results here

Interesting--I wonder if Tableau Server tries the credentials first, then retries with none if the server tells it that no authentication method is supported. I bet we could implement something like that in VizAlerts to help make things a bit easier in configuring.

Hi, Matt!

Sorry the delay to give a feedback, I only had a chance to test the new setting with the user today... And it worked fine - no other errors appeared!

Giving that, I think that Tableau Server really tries to connect to the SMTP server without credentials at some point...

Thanks sooo much for the help!

Hello,

I wanted to clarify where the changes to 'null' were made. Were they made in the SMTP settings on the 'Configure Tableau Server' menu or elsewhere? Wouldn't setting the SMTP credentials to 'null' affect subscriptions?

Thank you in advance!

Good catch--definitely do not modify your Tableau Server config! I was referring to the config\vizalerts.yaml file. You would make the change there.
