Error sending to the following VALID addresses Jenkins

Question

I will receive emails when I trigger using build now manually, but I don't receive emails when I tried to using it in batch mode. Below is the log I obtain when triggered in batch mode.

Email was triggered for: Always Sending email for trigger: Always Sending email to: [email protected] Error sending to the following VALID addresses: [email protected]

Note: There are no build logs attached while sending email.

Answer 1

In your Jenkins configuration, make sure that you have entered correct email address for "System Admin e-mail address".

Notification e-mails from Jenkins will be sent with this address in the "from" header.

Answer 2

Error - Not sent to the following valid addresses: <valid_recipient_address> OR Error sending to the following VALID addresses: <valid_recipient_address>

Reason - Email address of sender is not correct.

How to troubleshoot - Enable the debug mode from Jenkins -> Manage Jenkins -> Configure System -> (Search for Extended E-mail Notification configuration -> Check Enable Debug Mode
