I haven't been able to sort out how to reply by email. Emails are coming from the default admin address, not the address I created for P2 by Email. I don't want to change the admin address to the P2 by Email address (since, I obviously still want all other admin-type notifications to go to the admin address). I'm not clear on how to connect the dots to make this work.
Thanks for the plugin by the way. I love the basic email notifications already, and I'm looking forward to getting the posting and replying by email to work.
