I can not find any sort of online help feature where users can assist each other.

I have a Yahoomail account, and have 2 x mailboxes in that, lets call them Gmail and DRmail.

I access my email through not through the app, but through a 3rd party android app called Bluemail.

At present, to view my non-yahoo mail either online or through my app, I have to go through a series of clicks to find out if I even have any mail - that's annoying with just 2 mailboxes, but if I had 12?????

What I want is for all 3 accounts to appear in just one combined inbox, with the ability to reply to them through whichever of my 3 accounts are applicable (in most cases the one it was sent to).

If this can be done in Yahoomail, will it still appear as one inbox once accessed via imap?

Another issue is that I would like to set up subfolders in this combined inbox, so (for example) using filters, all my eBay emails come into the same subfolder, no matter which email ebay sent to - I have 2 accounts and therefore they mail me on 2 different emails.
