Make jenkins send email via sendmail

Question

I got a nullmailer setup to a 3rd party SMTP relay. It's working well.

How can I tell jenkins to send his email through the sendmail system function ?

I tried setting the SMTP credentials directly in jenkins, but it's a mess with TLS (none of the solution I tried worked with Mandrill)

Thanks.

I run into this problem today. If you don't want to setup a smtp provider such as gmail, you can install postfix (see here about how to install postfix non-interactively) on the maschine/container on which Jenkins is running.

Make sure postfix runs well. In my case postfix did not start automatically after installation.

service postfix start

Then in Jenkins select Manage Jenkins => Configure System => Email Notification. Enter localhost In field "SMTP Server". Let Jenkins send out a test mail to test it.
