重新生成imap ssl证书

   最近有同事反应用Thunderbird接收邮件时，总弹出证书到期的对话框，现重新生成证书后解决：
生成证书命令：mkimapdcert

# mkimapdcert
/usr/lib/courier-imap/share/imapd.pem already exists.             //发现此过期证书存在

# cd /usr/lib/courier-imap/share/
# mv imapd.pem imapd.pem.20090510     //更改旧证书文件名

# mkimapdcert         //重新生成imapd.pem文件

This is going to take a long time
