Motorola Droid 4 :: Cannot Fetch Email If Account Type Is Not 'Other'

I am adding Email definitions for my Gmail accounts (in addition to the Google account definition for Contacts, etc.) because I want them to appear in the Messaging -> Universal Inbox. (I'm not fond of the Gmail app.)

Similarly, I am adding definitions for my Hotmail accounts because I read somewhere that Moto/Verizon will set them up as IMAP which I cannot achieve through a client like K9, else I would probably just be using it for my Universal Inbox.

Via My Accounts -> Add account -> Email Accounts... If I set up a Gmail or Hotmail account by selecting Other and then automatically or manually configuring, then mail is retrieved. However, if I select the appropriate icon for Gmail or Windows Live Hotmail, the only Email which ever appears in the 'Inbox' is from donotreply@vzw.net regarding the success of the operation - this message is not even sent into my actual Gmail/Hotmail Inbox as verified online.. NONE of the other messages from my Inbox ever appear.

So, why do I care how the account is set up? Mostly because the only easy way to distinguish between the message source in the Universal Inbox is the little icon designating the type of Email account. If they are all set up as Other, they all end up with the same icon.

This functionality worked just fine on my Droid 2. So, is it now broken on the Droid 4?

(As an aside, the Hotmail account is set up automatically as POP3. Was I misinformed that Motorola had a license to set up as IMAP through some licensing agreement with Microsoft?)
