I found out we seem to have a problem with incoming emails not being updated into redmine. Our setup goes via Google Apps, and the messages get forwarded to our postfix-server:

user sends message to that is handled by googlel apps. The message get's routed back to our redmine-server that responds on

In postfix i have configured an alias that runs the rdm-mailhandler.rb

/usr/local/rvm/rubies/ruby-2.3.0/bin/ruby /etc/postfix/rdm-mailhandler.rb \
--project support   \
--tracker New issues \
--unknown-user create \
--no-permission-check \
--no-check-certificate \
--url https://redmineserver.ourdomain.tld \
--key [randomstuff] \
--allow-override all \
--no-account-notice \
--default-group Support

I still get though the following error

"permission denied. Command output: Request was denied by your Redmine server. Possible reasons: email is sent from an invalid email address or is missing some information" 

This is my currentn setup

I am having the same problem. I looked in the production log and I see the error:

MailHandler: ignoring email from unknown user []

But this is for an email from myself and I am a valid user on the project and Redmine admin as well. Sometimes my emails work, but most of the time I see this error and my email is bounced back.

I see nothing obviously odd about the emails that work versus those that do not.

I am running Redmine 3.2.8 but otherwise same Ruby and Rails as on this issue. I did not see any closed issues on this topic but I could try upgrading. Let me know if I should open a separate issue.
