Inviting users with internationalized emails

[coding-red-panda]

Hello,

we currently rely on devise_invitable to invite users to our application. However, some of these users have internationalized emails from Germany. For example: Maß[email protected], and devise doesn't seem to like this:

Net::SMTPSyntaxError: 501 Syntax error in parameters or arguments is what we receive when trying to invite such a user by calling invite!.

Any way we can make this work for such emails?

DeviseInvitable only add a method to Devise mailer to send invitation email, so probably error is in devise, ActionMailer or smtp.

That error is raised by ActionMailer, because it got smtp error, so it could be a bug in actionmailer or smtp server. Please check if you can send emails with ActionMailer to that address, or if you can send reset password email or confirmation email to that email address.
