郵件收取用戶端LumiSoft類庫接收yahoo郵件的問題。

1. //開始循環取郵件資料                  
2.                                     m_pImap.Fetch(  
3.                                                 false,  
4.                                                 IMAP_t_SeqSet.Parse("1:*"),  
5.                                                 new IMAP_t_Fetch_i[]{  
6.                                                 new IMAP_t_Fetch_i_Envelope(),  
7.                                                 new IMAP_t_Fetch_i_Flags(),  
8.                                                 new IMAP_t_Fetch_i_InternalDate(),  
9.                                                 new IMAP_t_Fetch_i_Rfc822Size(),  
10.                                                 new IMAP_t_Fetch_i_Uid(),  
11.                                                 new IMAP_t_Fetch_i_Rfc822()  
12.                             },  
13.                             this.m_pImap_Fetch_MessageItems_UntaggedResponse  

上面的代碼是直接收取郵件，包括頭字段和郵件正文。

 ​

​​

1. new IMAP_t_Fetch_i_Rfc822()  

注意，這句話是表示接收郵件的正文，而我經過測試，發現這段代碼在接收yahoo郵箱的時候，郵件不能收取完全，是以在收取其他郵箱伺服器的時候，可以采用上面的代碼進行整體收件。

是以可以改成下面的這段代碼

1. if(ip=="apple.imap.mail.yahoo.com")  
2.                                 {  
3.                                     //開始循環取郵件資料                  
5.                                         true,  
6.                                         IMAP_t_SeqSet.Parse("1:*"),  
7.                                         new IMAP_t_Fetch_i[]{  
8.                                             new IMAP_t_Fetch_i_Envelope(),  
9.                                             new IMAP_t_Fetch_i_Flags(),  
10.                                             new IMAP_t_Fetch_i_InternalDate(),  
11.                                             new IMAP_t_Fetch_i_Rfc822Size(),  
12.                                             new IMAP_t_Fetch_i_Uid(),  
13.                                             //new IMAP_t_Fetch_i_Rfc822()  
14.                                         },  
15.                                         this.m_pImap_Fetch_MessageItems_UntaggedResponseyahoo  
16.                                     );  

這裡實際上就沒有采用直接收取正文的方式，實際上，這裡隻是收取了頭字段。那麼應該在其他地方繼續寫收件的代碼。
