Redmine sends mail twice

Question

When creating/editing an issue in redmine the notification mails get sent twice. Why?

I looked into the redmine configuration file "config/configuration.yml" and tried to remove the "email_delivery:" section in "production:" because there is already one defined in "default:"

Even when using the "Send a test mail" feature of "Administration > Settings > Email notifications" the test email gets sent twice.

But this only occurs when using the below ":sendmail" configuration. When using ":smtp" and setting an SMTP server the mail gets correctly sent only once. When using the commandline "mail" command mails also get sent just once.

This is how my configuration.yml looks like:

production:
  email_delivery:
    delivery_method: :sendmail
# ... comments ...
default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :sendmail
# ... other stuff

The mailer which is used is qmail. This is the output of mail.info for sending a test mail:

It seems the ruby ActionMailer is already causing "to=kraft@web-consulting.at" twice.

Any ideas?

Answer 1

Maybe you have an old version of sendmail?

  config.action_mailer.delivery_method = :sendmail
  config.action_mailer.sendmail_settings = {
   :location => '/usr/sbin/sendmail',
   :arguments => "-i"
  }

For me, I had to use sendmail with -i to fix the double-send problem
