rubygems

问题 I'm currently using gem called "Mailboxer" on rails3. Everytime, mailboxer delivers email, and it seems it's using the template shown below. Anyone knows how to customize this template?

问题 Just integrated Mailboxer and I'm running into one problem. When I send a new message the sender_id in the mailboxer_notifications table is always zero instead of the id of the sender.
