Question

First of all you have to know I’m total Ruby noob 🙂

I installed git-commit-notifier (http://github.com/ilozka/git-commit-notifier) on my system (Ubuntu 10.04) and followed all the installation instructions but every time I push to my git repository I get this error message:

remote: Sending mail...

I tracked the error to emailer.rb script. Specifically line:

Net::SMTP.start(settings['address'], settings['port'], settings['domain'],                                                                                                                             
                settings['user_name'], settings['password'], settings['authentication']) do |smtp|

The parameters seemed to be passed correctly (i have checked that).

My config script looks like this:

# select the delivery method: smtp or sendmail
delivery_method: smtp

# settings for the smtp server
smtp_server:
    address: smtp.gmail.com
    port: 587
    domain: mydomain
    user_name: [e-mail]
    password: xxxxxx
    authentication: plain
    enable_tls: true

Does anyone know how I can solve this issue? I have Redmine on the same server and it works fine. No problems with email sending.

Thank you

Net::SMTP does not seem to support STARTTLS. This question offers a solution to that problem by monkey-patching Net::SMTP to do just that.
