ActionMailer with SMTP - Bad recipient address syntax

My user has email with this format: "[email protected]". Mailgun validation succeeded but Rails couldn't send email to the address. I'm using SMTP with Mandrill. This is the error message: 

/home/johnny/.rvm/rubies/ruby-1.9.3-p448/lib/ruby/1.9.1/net/smtp.rb:948:in `check_response': 401 4.1.3 Bad recipient address syntax (Net::SMTPServerBusy)

Do you have any idea?

Thanks in advance.

Updated:

This sample code (with valid SMTP configuration) would raise the error:

#!/usr/bin/env ruby
require 'mail'

options = {
    address:      "smtp.mandrillapp.com",
    port:     587,
    domain:     "mydomain.com",
    authentication:   "login",
    user_name:    "[email protected]",
    password:     "mypassword",
    enable_starttls_auto: false
}

Mail.defaults do
    delivery_method :smtp, options
end

Mail.deliver do
    from '[email protected]'
    to "[email protected]"
    subject 'Testing sendmail'
    body 'Testing sendmail'
end

Even if the starting dash in the email address is valid, most mail servers do not accept such emails due to restrictions for command line arguments.

A quick fix you can try is wrapping the email address with angle brackets:

Mail.deliver do
  from '[email protected]'
  to "<[email protected]>"
  subject 'Testing sendmail'
  body 'Testing sendmail'
end
