To add a new POP account, you don't need to add a new mailbox by File >
Add Mailbox > MH..., you only need to add a new account by the
Configuration menu.

Take a look at
Configuration > Edit Accounts... > Some Account > Receive > Default Inbox
Configuration > Edit Accounts... > Some Account > Advanced
and edit it for all accounts, to select the same MH.

Care that no filter or anything else does use a different MH and
after moving the mails you want to keep, remove all the MHs you don't
need, by right-clicking on the mailbox and selecting
Remove mailbox... .

I'm using several POP accounts and only have got one MH and there never was a
MH created, when I added a new POP account.
