解决cyrus-imap中文邮件标题“XXXX”问题

因RFC规定数据格式,为7bit,而8bit编码的中文标题被cyrus-imap给用XXXX取代掉了，查证cyrus-imapd的文档。将这个功能关闭，问题解决。

munge8bit: 1
If enabled, lmtpd munges messages with 8-bit characters in the headers. The 8-bit charac-
ters are changed to ??X??. If reject8bit is enabled, setting munge8bit has no effect. (A
proper solution to non-ASCII characters in headers is offered by RFC 2047 and its prede-
cessors.)

在/etc/imapd.conf里加入如下一句：

munge8bit:no
