Thanks. That saved my day!

I just came across one issue in the parse_email function: a crash will result from improper access to the returned array.
It seems that entries in a map like this x={:login=>"a", :domain=>"b"} can only be accessed via x[:domain] and not like this x["domain"] the later is the form that the code is using to refer to the map entries.

my fix was to change how the index is set in the returned map in lib/helpers/mail_helper.rb to
{"login" => email_data[1], "domain" => email_data[2]} if email_data

My system specs :

  Redmine version                3.4.5.stable
  Ruby version                   2.4.3-p205 (2017-12-14) [x86_64-linux]
  Rails version                  4.2.8

Otherwise all worked well as expected.
Thank you again!
