Redmine

The authentication parameter is :plain, not :plan. Other than that, gmail needs ssl stuff, see here: http://redmineblog.com/articles/setup-redmine-to-send-email-using-gmail/ (that might be a tad outdated though, so take it with a grain of salt and maybe google for "rails gmail" for more/complementary help).

I used this gmail conf sample http://www.redmine.org/wiki/redmine/EmailConfiguration without any trouble

Well, use your brain and tell me what these 2 pieces of information put together tell you?

I've had same issue, but finally solved it by using
authentication: :login insted of authentication: :plain

I got the hint from redmine email configuration documentation (http://www.redmine.org/wiki/redmine/EmailConfiguration) which says at the top that the valid setting for authentification is :none and :login.
(However, gmail smtp example below uses authentication: :plain. The documentation needs to be updated)
