Sergey,

I think I failed to properly frame the problem.

Here is what I have:
A generic gmail account of my name: jeffbxxxx@gmail.com.
Under that I have jeff@domainx.com and jeff@domainy.com.
I can log into gmail desktop browser using any of the above addresses and password. All of the mail goes to the same inbox.

On the N9 I cannot create a gmail inbox using either of the jeff@domain addresses but I can the jeffbxxxx@gmail.com.

I can only only create one MFE inbox for the jeff@domainX/Yaddresses. It can be one or the other but not both.

Whenever I try to create the second it tells me that it exists even though it does not.

The only thing I really care about is the ability to select either of the jeff@domain addresses as the sender field when composing an email. It does not matter to me if they all come to the same inbox. It also would not matter to me if they were all separate inboxes. Cumbersome/clunky-yes, functional yes.

Right now I have selectable jeffbxxx@gmail.com and jeff@domainY.com under the dropdown for the sender field.

In android when I setup the one gmail account all of the reply/sender options were populated and I could easily select the one I wanted.

To me, it would seem the ability to merely add a "sender/reply to" field would be doable and easiest, but then I'm not doing the stuff you are.
