I am trying to import from Eudora v6.x to Thunderbird v3.x on a Mac. I have about 6.5 GB of mail, attachments, filters, etc.. representing over 10 years of e-mail. I have let the imports run over eight hours and it is still running. When I look at the Library/Thunderbird folder, it looks like the mail folders are set up, but I don't think the e-mails themselves have yet been imported. CPU usage after an hour or so drops to the 1% range.
How long should it take to import?
I'm running a MacBook Pro 15" 2.4 GHz purchased in Nov. 2007. I have 4 GB RAM. I'm running Snow Leopard (v10.6.3).
