Splunk could send email after the upgrade from 6.5 to 7.1 (ERROR sendemail:460 & ERROR sendemail:137)

[dashalfy]

Hi there,

I have performed a version upgrade from 6.5 to 7.1 and found that the Splunk instance becomes unable to send emails (scheduled reports and triggered alerts).

The error messages are as follow:

splunk_python:
ERROR sendemail:460 - {u'user@companydomain.com': (454, '4.7.1 : Relay access denied')} while sending mail to: user@companydomain.com

ERROR sendemail:137 - Sending email. Subject="Report subject", results_link="https://mysplunk:8000/app/search/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", recipients="[u'user@companydomain.com']", server="email_server_ip_address"

Would any have hit this issue before/ any clues on solving this issue?

Many thanks!
Regards,
AL

Check whether the mail server that is being used currently to send the triggered alert, is a correct one with respect to your environment. If it is correct, check with your company's network team that whether any firewall is blocking.
