I have a very simple Umbraco site. I can send "forgot password"-email when running the site from localhost, but when I deploy it to my azure app service I get the error message

"Request password reset failed for email forgetfulbackoffice[email protected]"

this is from my web.config and umbracoSettings.config.

Im also interested in how to diagnose this problem. I have looked in \app_data\logs, but I cant see any error message that is related to sending mail. In the Umbraco-db, the table UmbracoLog has merely 30 rows, non-related.

[mailSettings]
  [smtp deliveryMethod="Network" from="[email protected]"]
    [network defaultCredentials="false" host="smtp.gmail.com" userName="[email protected]" password="yyyyyyyyy" port="587" enableSsl="true" /]
  [/smtp]
[/mailSettings]


 [notifications]
  [!-- the email that should be used as from mail when umbraco sends a notification --]
  [email][email protected][/email]
[/notifications]

EDIT: Ive got it to work with an office365-account instead of gmail. Still curious why it doesnt work and how to diagnose the problem.
