邮件收取客户端LumiSoft类库接收yahoo邮件的问题。

[csharp] view plain copy

 

 

1. //开始循环取邮件数据                  
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  

上面的代码是直接收取邮件，包括头字段和邮件正文。

[csharp] view plain copy

 

 

1. new IMAP_t_Fetch_i_Rfc822()  

注意，这句话是表示接收邮件的正文，而我经过测试，发现这段代码在接收yahoo邮箱的时候，邮件不能收取完全，因此在收取其他邮箱服务器的时候，可以采用上面的代码进行整体收件。

因此可以改成下面的这段代码

[csharp] view plain copy

 

 

1. if(ip=="apple.imap.mail.yahoo.com")  
2.                                 {  
3.                                     //开始循环取邮件数据                  
4.                                     m_pImap.Fetch(  
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.                                     );  

 

这里实际上就没有采用直接收取正文的方式，实际上，这里只是收取了头字段。那么应该在其他地方继续写收件的代码。

[csharp] view plain copy

 

 

1. //调用读取邮件函数  
2.         private void LoadMessage(long uid)

10.                     new IMAP_t_Fetch_i[]{

98.         }  

也就是说，收取邮件头和邮件正文分开，这样就能收取包括yahoo在内的所有邮箱。代码是直接从我的工程文件里面拷出来的，作为参考，不能直接使用，但是保证是一定可以用的，更多问题可以联系我。
