Mac Mail and Gmail

[SevenEleven]

I am having problems with my mac mail and gmail. It was consistent across my iphone, imac and macbook. Only with one gmail account, the other is fine. It tells me there is a username or password error. I know this isnt the case because I have tested it by logging into the web version of gmail.

I have tried deleting and recreating the account - still the same problem. On my iphone the problem was fixed by using exchange.

Any advice?

Thanks

Are you using IMAP or POP3?
You need to make sure it is activated in GMail's settings.

Set-Up for IMAP is here: http://mail.google.com/support/bin/answer.py?hl=en&answer=180188

Sorry if this is irrelevant!

Yes thank you for the reply. I have been using Imap all along. This just suddenly started to happen recently.
