That's unrealistic to say "don't use this" when it may be part of the solution.
However, if I wanted to move mail around my favored method uses Thunderbird. I use an email client that can fetch my email and keep it under my control. Those web email systems are subject to change and loss. You can't count on them.
So for this round I'd use Thunderbird to fetch all my emails then try methods from https://www.google.com/#q=thunderbird%20upload%20email%20to%20server
Excite has been garbage for almost a decade since they were purchased by BlueTie. Got it. I still use it because I have some valuable emails on the server BUT I can't search the contents of emails because the search tool only allows search by subjects, Sender or recipient. So I want to move all my email to GMAIL but You can't do that as a regular subscriber, you have to upgrade to the Gold membership. The only issue is BlueTie is not accepting Gold memberships and to the best of my knowledge has not for nearly 5 years.
So do any of you how to Export a bulk of email to GMAIL WITHOUT the use of pop3?
