We have a new client that wanted to move their web hosting and e-mail. We set up most client’s e-mail in Google Apps for Your Domain. However, this client is only using their webmail feature and is not using any mail client on their computer to download e-mail.
Our old method was to download the e-mails to Outlook Express, then export them but this client just wants to continue using a web-based e-mail and their mobile phone for checking and sending e-mail.
So, we set up a Google Apps account and created an e-mail address that was different from the one we wanted to pull from. For example, we set up the Google Apps account at mydomain.com. We created an e-mail address such as email@example.com. We opened the e-mail address, firstname.lastname@example.org, clicked on Settings, Accounts, and set up the POP settings for their e-mail account (email@example.com) at the other server. Once we clicked Next, the e-mails all were pulled into the online e-mail account. This is before made any DNS setting changes for the MX records.
So, now all the client’s e-mails are in the new account and we can change all the MX settings and the client is happy!
