What happens if I turn on POP and keep IMAP on my Gmail account? Will it affect the way emails are delivered to my X? If I delete an email from my X, will it still be on the Gmail server for access via Thunderbird? Reason I'm asking is this past week's problem with Gmail made me think that all my online purchases, receipts I store on Thunderbird are really kept somewhere else. If I had a POP account, all that information is downloaded to my laptop, that is backed up weekly, so most would not be lost if there was a problem with the Gmail server. But, not sure what would happen if I checked off POP with IMAP also checked. Thanks in advance for any information.
