My Eudora with POP stopped working when yahoo changed their security several times, so I installed Thunderbird and have used that for a few weeks. I have three email accounts which read and write correctly with Thunderbird / yahoo mail. I now want to install all the Eudora mail folders( 100+ of them) and the Eudora filters, and arrange it so that every incoming email to any of the three accounts is filtered and sent to the correct mail folder. how do I do this please? kind regards, Joe
