I recently signed up the netinlet.com email for Google apps for you domain

I had all my mail funneling to a gmail account to begin with, so I need to get all that email from the first google account to the new google apps account.

You can do with with POP, but you have to put in a different pop server name. Use pop.googlemail.com instead of pop.gmail.com. pop.gmail.com will not allow you to access via pop. Go figure.

Everything else stays the same, just make sure to use ssl on port 995.

The process takes a while. Mine has been running for about a half an hour and has only pulled over 300 emails so far. I have mine setup to pull over all email, so everything (INBOX, SENT, ARCHIVED) gets stuck into the inbox on the google apps account.
