Well, even if you are able to forward account B to gmail account A,
Google may decide to reject a portion of those at SMTP time, so the
"solution" is to point account A to *also* fetch the emails from B
through POP, so they end up downloaded in that other way.
Corporate version does have an option to trust a sender MTA as part of
your organization (at the org level, I think), but normal users have to
use this kind of duct tape. 

For extra fun: Gmail will also perform "SPF checks" on those POP-
downloaded mails and decide on whether they are spam or not based on
the (sometimes quite wrong) IP addresses it guesses…
