When receiving a reply to a locked topic, mail handler crashes with the following error:

  undefined local variable or method `sender_email' for #<MailHandler:0x0055675dfa9e10>
Did you mean?  send_action
  app/models/mail_handler.rb:289:in `receive_message_reply'

That's because receive_message_reply is trying to use sender_email variable, which was not defined in this method.
Here is the corresponding line (source:trunk/app/models/mail_handler.rb@18198#L277):

logger&.info "MailHandler: ignoring reply from [#{sender_email}] to a locked topic"
