Received this error message when I tried to download new email with Thunderbird this morning: "The POP3 mail server (pop.verizon.net) does not support UIDL or XTND XLST, which are required to implement the ``Leave on Server, ``Maximum Message Size or ``Fetch Headers Only options. To download your mail, turn off these options in the Server Settings for your mail server in the Account Settings window." There is no where in my Server settings that even has these options, much less to turn them off. Fetch headers only was off already, & no maximum message size set. When I turned off Leave on Server, all the new email downloaded, but all my email disappeared from other devices, so I turned it back on. How do I correct this while retaining the Leave on Server setting?
