I've been playing around with cucipop, but I can't seem to make it work with mutt. Running cucipop in debug mode, all seems to fine: after specifying USER and PASS, I can LIST and STAT, the mailbox, RETR messages etc. But mutt (1.3.19) only ever tells me that APOP authentication failed, "Fetching list of messages ...", and then quits. I compiled cucipop with and w/o APOP, ran it with and w/o -A, no luck. So, who's the culprit here?
