redmine:email:receive_imap broken with ruby < 1.6.3 and Google Imap
referring to this message I opened in the forum
I'm on the latest Redmine 4.0.4 on my Ubuntu 18.04;
Ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]
Phusion Passenger 5.0.30
Since a couple of days I've always used to generate new Issues from email, fetching from several gsuite (gmail) accounts.
Here is a sample of one of my many crons:
/8 * * * * /usr/local/bin/rake -f /usr/share/redmine/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=imap.gmail.com port=993 email@example.com password=my_password ssl=1 folder=issues_folder project=my_project priority=Normal tracker=MyTracker move_on_success=read move_on_failure=failed unknown_user=create default_group=default_group no_permission_check=1
It has been working since a couple of years but starting from Wednesday (probably) it stopped.
Here is the error I get with a --trace:
** Invoke redmine:email:receive_imap (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute redmine:email:receive_imap rake aborted!

I found out the problem has been patched in ruby 1.6.3
maybe redmine should be "fixed"? In my ubuntu 18.04 I needed a manual patch (ruby 2.6.3 not available as update, and I did not want to install it manually)
if you need further information just ask.
