我尝试解析其正文为csv格式的电子邮件。
电子邮件据说有这样的内容：
,111111111111111,Abcde Abcd,,abcde@abcdefghi.com.au,61352722827,13/04/2012,14/04/2011,Abcd Abcdefghi,
,111111111111111,Abcde Abcd,,abcde@abcdefghi.com.au,61352722827,13/04/2012,14/04/2011,Abcd Abcdefghi,
但是imap_savebody（）会像这样保存它：
,111111111111111,Abcde
Abcd,,abcde@abcdefghi.com.au,61352722827,13/04/2012,14/04/2011,Abcd
Abcdefghi,
,111111111111111,Abcde
Abcd,,abcde@abcdefghi.com.au,61352722827,13/04/2012,14/04/2011,Abcd
Abcdefghi,
由imap_fetchstructure输出的编码是7BIT。谁知道为什么会这样？
