I just downloaded T'bird. It worked for a few days. Then I got an error message that said, "The POP3 mail server (inbound.att.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." I did this, but it erased the messages on my phone. How do get the messages back on my hone and how do I fix the T'bird error message. Please reply to wks8@att.net. Thank you.
