Long-time Mac user, curious why, from time to time, Mail settings just plain disappear.
I only discover this when Mail suddenly can't connect. Have to input passwords again.
And not the same password or place (several email accounts.) Could be the server p/w missing, or the POP3. One of life's little mysteries, has persisted since at least Lion.
The keychain entries are fine, the keychain and in fact whole system well-maintained. So where do they go? What erases them and why?
