Running redmine in docker getting ssl error, any ideas what might be the issue?

[rafaelteb]

Hi there! I would appreciate any sort of help a lot ;) Not getting much further with installing this nice redmine plugin.

Here are the two problems:

1. SSL issues
2. No mailbox error

1. SSL issues When I turn of ssl with some dirty script, the plugin is sort of working (but still getting errors). Here is the script, located in /usr/src/redmine/config/initializers/bypass_ssl_verification_for_open_uri.rb:

require 'openssl'
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

Any ideas? I allready connect with openssl s_client -connect to my email provider, it says it connects:

CONNECTED(00000003)

I also tried adding it to .bash_profile with exort SSL_FILE=/user/../../cacert.epm (did not work)

Here is info about my current system:

RAILS_ENV=production rake about

2. No mailbox error Like I said, the plugin is sort of working: It gets me 1 email (and 1 only, not the rest thats in the remote mailbox) and shows a lot of error messages:

Tasks: TOP => redmine:email:receive_imap

I guess I have to add a mailbox somewhere, I tried adding folder INBOX to the root of the app, but that did not help.

Any help would be very much appreceated!

Best regards

Ok my bad. Mailserver had issues. Got another wierd error now though:

 ERROR -- : MailHandler: an unexpected error occurred when receiving email: undefined method `value' for nil:NilClass
rake aborted!
Net::IMAP::NoResponseError:  No folder failed (Failure)

Any idea what that is about? Also appeared here 5 years ago ;) : https://www.redmine.org/issues/13485
