I list many free IMAP providers on my IMAP Service Providers
page, starting in this section:
There are more in The List that is immediately below The Table.
If you are going to be using IMAP, I recommend avoiding Eudora,
whose inventor famously said "LDAP is an *** " and "I'm
really looking forward to the day when people get IMAP and find
out just how much it sucks." The IMAP clients that I use
and recommend are:
Pine (both Unix- and PC-Pine)
I haven't yet used Thunderbird, which is part of the Mozilla
Project, but a lot of people like that too.
Hope this helps,
