I use Thunderbird with IMAP mail accounts and don't sync any mail locally. When adding a new IMAP gmail hosted account the default at account creation is to start syncing mail locally. Once syncing starts (usually the inbox) it won't stop until the sync is complete. My current procedure to add a new account is to add the account, leap into settings, turn off "Keep messages for all folders for this account on this computer" and then quit Thunderbird before syncing starts. I then restart Thunderbird and repeat the procedure for the next account. Is there a way to start Thunderbird so the default on creating a new IMAP account will NOT be "Keep messages for all folders for this account on this computer" to save having to quit and restart each time. Thanks.
