I am migrating from Google Apps for Domains to a self-hosted service. After removing my Google account from Mail, and attempting to add my self-hosted account, Mail and System Preferences always default to Google as the provider for my email. DNS records have been switched (mail flow works fine from my self-hosted service).
Every time I attempt to add a new account, it assumes I want the Google account it discovers and not my personal email.
I have uninstalled Gmail from the Google Apps for Domains control panel, but this has not helped (yet). I have also removed my preferences folder for Mail.app, but this does not help either.
I cannot delete or rename this Google account; other services are attached to it.
Any suggestions?
I had previously thought that by changing the passwords to differ after uninstalling Gmail, it was working. However, while it lets you add a different IMAP account, the type is still "Google IMAP", which causes issues when trying to setup the accounts properly (most notably because I also have a self-hosted CalDAV account).
After further testing, I have found that any IMAP account I attempt to create is set as a "Google IMAP" account once I provide the self-hosted domain (meaning, even if I create it with fictitious information and later supply the domain only when I have to). How can I address this?
