Bug in the User activation email about ci-global-calendar

[davide-casiraghi]

To send email from the website we use Mailgun mail server.

Checking online the logs on Mailgun I found this error:

Failed: [email protected] → [email protected] 'New user
registration' Not delivering to previously bounced address

Here Mailgun documentation about:
https://help.mailgun.com/hc/en-us/articles/360012152213--Not-Delivering-to-Previously-Bounced-Address-

[davide-casiraghi]

To solve go to Mailgun > Suppressions page and delete the bounced address from the Bounces list.

I've solved even if I didn't get why the admin email went to the bounce list.
Since we have the free version of Mailgun the log was not enough old to see the cause.
If it happens again we will write to Mailgun support to ask further details.

This issue happened again on 30/3/2019.
I've opened a ticket to Mailgun asking for support.

The support of Mailgun add the admin address in the suppressions whitelist, so this bug will not present any more.
Below I paste the answer from the support.

Hi There,

Thank you for contacting Mailgun support.

I have gone ahead and added [email protected] to our suppressions whitelist. This way this email will not be added to the suppression list anymore.

Please let me know if you have any questions.

Thank You,
Michael | Mailgun Support
