Any suggestions would be great...

BIS doesn't regognize my domain and know how to handle it like a Gmail domain as it is.

I doubt there is a solution but any light on the issue would be great!

Who knows, RIM may find hosted Gmail not suitable for BIS or the most likely issue that they probably don't have this implemented yet.

Not positive exactly what you're asking, but if I'm guessing right - if you go to set up an email account on BIS 2.x, all it asks for is email address and password. BIS "knows" the right info about all the common email services - regular gmail, aol, comcast, sbcglobal etc. If you put in an email address with a domain it doesn't recognize, then you'll be presented with a supplemental screen where you can manually enter in the detail info like whether its POP3 or IMAP, the POP3/IMAP server name, and the SMTP server name. By entering in the proper info on that screen, you should be able to add any account that offers either POP3 or IMAP interface.

I was looking to use the new BIS 2.1 Gmail push services with my Hosted Gmail service from Google.

This runs google's native Gmail protocol.

Don't know if Cingular has implemented BIS 2.1 for Gmail. Iunderstand the Yahoo integration doesn;t work on Cingular.

I am in the same situation as the OP. GMail now offers (Beta) hosted email.

I have one of my domains, richforeman.org, on this service. Basically, you get hosted email that works on the gmail engine and has all of the features of gmail.

to log in to this, you have to log in with and password, and BIS is not working with this because, I think, it doesn't recognize that the service is actually on a GMail server..

It's a common problem, most services that support GMail integration (Google Talk for example) don't work with the hosted mail service (I use it, too). Until it comes out of "beta" (although GMail itself is still considered "beta"), I don't know if it'll get supported by BIS.

I ended up setting up rules in my mailbox to forward certain messages to my @vzw.blackberry.net address and then set a BCC back to myself on sent messages so they go back into the hosted Gmail account. It was a bit of a pain to set up, and I end up seeing the messages twice, but it's functional.

Yes, I too have the GMAIL/HOSTED DOMAIN EMAIL SERVICE. I have the same problem, I want the same functionality that GMAIL users get with my GMAIL hosted email. Not sure how we go about it, but I would LOVE it
