Cannot access email through MAIL app

[musiqzuki]

Hey there,

I have several email accounts synced with the Mail app that comes with Mac OSX.

I used to be able to access email fine, but now I can never retrieve email from it. I constantly get the icon with a triangle and an exclamation mark beside the mail boxes.

Funny thing is, I my internet is fine, and I can access the email through it's website. So what's up with not being able to retrieve email through the Mail app?

Thanks

What provider do you use? GMail, Hotmail, Mobile Me etc? Im not sure if it will help, but it could.

I have a gmail account :S

My ADIUM, wasn't working too until I changed the account settings to "Connect via HTTP"

So I'm assuming there's something similar like that I have to change in the Mail app, but I dunno what.
Is it a port issue? :S
