I was testing some email servers and added several email accounts to my Mac. I deleted these accounts afterwards.
Now I have only three base accounts in System Preferences > Internet Accounts
: Facebook, Twitter and iCloud.
However, Mail Connection Doctor (Window > Connection Doctor
) still attempts to access the deleted accounts; if one of them has invalid credentials or settings it reports "Mail can't connect to the account."
Where these accounts are stored and can I permanently remove them so the Mail Connection Doctor doesn't try to connect?
