Description
In CRM/Mailing/MailStore.php, the getStore method is expecting $dao->protocol to return one of 'IMAP', 'POP3', or 'Maildir'. However, it gets the "value" field from the DB, which just has integers in it. 1 for IMAP, 2 for Maildir, 3 for POP3. So no protocol ends up matching and the processing doesn't take place.
This is in alpha2 w/ a couple alpha3 revisions applied so the mail server field shows up in the admin tool.
