我能够检索电子邮件并浏览各种文件夹。但是，由于证书错误（如下所述），我无法发送任何电子邮件。互联网上的一些配置提供了证书文件的路径，但 OSX 使用钥匙串代替。我在 Google 上没有找到任何描述如何为 OSX（Mountain Lion）进行设置的内容。任何帮助将不胜感激。
[我正在not使用 gmail。]
互联网上的其他用户引用了与此类似的配置： (setq ssl-program-name "gnutls-cli" ssl-program-arguments '("--port" service "--insecure" "--x509cafile" "/etc/ssl/certs/ca-certificates.crt" host)) 但是，由于使用钥匙串，OSX 上没有此类证书文件位置。我假设这是问题所在，但我并不完全确定。
我在使用 gnu 电子邮件时遇到了同样的问题，文档指出：
The SMTP server may also request that you verify your identity by sending a certificate and the associated encryption key to the server. If you need to do this, you can use an ~/.authinfo entry like this:
machine mail.example.org port 25 key "~/.my_smtp_tls.key" cert "~/.my_smtp_tls.cert"
这是我目前的配置：
(setq ssl-program-name "/absolute/path/to/gnutls-cli"
ssl-program-arguments '("--insecure" "-p" service host)
ssl-certificate-verification-policy 1)
(autoload 'wl "wl" "Wanderlust" t)

这是发送电子邮件时的错误消息：
