Redmine

Tracker notification emails sent out by Redmine are lacking the To: mail header in violation of RFC2822.

This is reproducible for me on two separate Redmine installations (one has Redmine 2.2.2 the other 2.2.3; both use Ruby 1.9.3 and Rails 3.2.12), and also with the primary Redmine tracker itself (i.e. the very tracker on which I am filing this issue right now).

There is, however, an Envelope-To header. I am a bit surprised by this, since app/models/mailer.rb looks as if it was explicitly setting To, CC and Subject headers at the same time... But then I am quite the ruby n00b, so perhaps this is "normal".

Anyway: It would be good if Redmine sent RFC compliant emails. E.g. some spam filters treat a violation of RFC2822 as an indicator for spam.
