Hi all,
My alerts were working fine till yesterday and no configs have been changed other than the device on which librenms is deployed was recently patched. After patching, I have started receiving error when trying to send email from librenms that SMTP host could not be found.
However, when trying to curl that snmp host from machine, I am able to reach it and getting proper response. Librenms logs are not showing anything relevant and I am not sure what can I check for this. Output of validate.php is provided below
