I need to be able to read email from an account on my Dreamhost server using a Rails app. I want to accept data and images via email if possible.
Can anyone point me to a tutorial or other resource that would help me accomplish this?
You'll need to create a controller subclass of actionmailer and define a receive method which handles the incoming email. Also consult the ruby documentatino on the Tmail class.
You'll need to set up an automated way to feed the email to the actionmailer controller. Procmail works well for that if Dreamhost provides it. run "man procmail" on dreamhost to see the documentation on procmail.
The book _Agile Web Development with Rails_ has a chapter on processing email in rails.
