I''m trying to figure out if I can use the ActionMailer and Rails for a IMAP reading application. It''s not a web mail application. But I don''t really see where the boundaries are for a Model, Controller, View. Or is it simply that everything related to reading the email via IMAP (which is going to be started from shell via crontab or other) is a Model and everything else, if I want to manage the results via my website, are all Controller/View issues... And this also leads into another email related question. Anyone use Rails for DNSBL?
