Eudora doesn't let me enter username separate from server
Apparently, old versions of Eudora (near 1.5.2) don't have separate fields for username and server. You are supposed to enter login@popserver.domain.ext and it will separate the username from the server.
If you enter username@mail.spamcop.net, you get a "login failed" message.
If you enter username@spamcop.net, you get a "Could not connect to spamcop.net. Cause: Connection refused (10061)" message.
Use username%spamcop.net@pop.spamcop.net
