mailer is not able to deliver email: Net::SMTPServerBusy

Sensu Classic (EOL)
1

Hi all,

I am not able to send out using mailer.rb (https://github.com/sensu/sensu-community-plugins/blob/master/handlers/notification/mailer.rb).

I use this command to test:

cat /tmp/test.txt |/opt/sensu/embedded/bin/ruby -d /etc/sensu/handlers/notification/mailer.rb

I got this error message:

I have double checked the /etc/default/sensu file and it contains

EMBEDDED_RUBY=true

LOG_DIR=/var/log/sensu

LOG_LEVEL=info

SERVICE_MAX_WAIT=10

My questions are:

  1. How can I fix 454 4.7.0 TLS not available due to local problem (Net::SMTPServerBusy)?

  2. Is it a proper way to test a handler? Do I still need to set a GEM_PATH?

Thanks, Tony

Hi all,

Find a solution: the problem was a missing ca cert

/etc/postfix$ sudo openssl req -new -x509 -nodes -out cacert.pem -keyout cacert.pem -days 3650
