mewを使わせて頂こうと思ったのですが
.emacsに
(setq load-path (cons (expand-file-name "~/.elisp/mew") load-path))
(autoload 'mew "mew" nil t)
(autoload 'mew-send "mew" nil t)
(if (boundp 'read-mail-command)
(setq read-mail-command 'mew))
(autoload 'mew-user-agent-compose "mew" nil t)
(if (boundp 'mail-user-agent)
(setq mail-user-agent 'mew-user-agent))
(if (fboundp 'define-mail-user-agent)
(define-mail-user-agent
'mew-user-agent
'mew-user-agent-compose
'mew-draft-send-message
'mew-draft-kill
'mew-send-hook))
.mew.elに
(setq mew-mail-domain "domain of e-mail address")
(setq mew-pop-server "your POP server")
(setq mew-nntp-server "your NNTP server")
を、記述し起動しようとしたのですが

起動の途中で死んでしまいます

mew-ssh-setup: Wrong type argument: stringp, nil
Commands: d, s, x, u; f, o, 1, 2, m, v; ~, %; q to quit; ? for help.

何が悪いのでしょうか？
