Mail: jmail, system. net. Mail, system. Web. Mail

I have been solving the problem of email garbled characters for the past two days. I have tried many methods and have no good solutions.

During the test, we used about three mailboxes, including Outlook, Hotmail, and Gmail. Generally, garbled characters are on Hotmail, And the charset is set to big5, in the text, the Chinese and English questions are mixed, and the Chinese characters are simplified and complex, so Hotmail is basically messy.

Start is sent with jmail, so change to UTF-8 or big5 are not good, not this mess, is another chaos ~

Then I heard that the systems used by other departments are not garbled. Later I found that the system was used. web. mail (this is already available in framework1.0, but the projects I have been using seem to have never done, and most of them have done system. net. mail, not implemented yet)

There is no big difference between moving and jmail. Here is only a few notes.
1. the email server may need to verify the correctness of the sender's address (I .e., from). The test email server does not seem to have checked this, so it is useful online, so it takes some twists and turns to check, then, you can spell the from statement as follows.

 

Code
Mailmessage. From =   " \ "" + Strmailfromname + " \ " < "   + Strmailfrom +   " > " ; // "\" John Smith \ "<you@yourcompany.com> ";
// Or
Mailmessage. From =   " XX@xxx.co " ; // The FROM address must exist in SMTP.

 

2. Other settings

Sample Code
System. Web. Mail. smtpmail. smtpserver = Strmailserver; // Mail. smtpserver;
Mailmessage. Fields. Add ( " Http://schemas.microsoft.com/cdo/configuration/sendusing " , " 2 " );
Mailmessage. Fields. Add ( " Http://schemas.microsoft.com/cdo/configuration/smtpauthenticate " , " 1 " );
// Email Password
Mailmessage. Fields. Add ( " Http://schemas.microsoft.com/cdo/configuration/sendpassword " , Strmailpassword ); // Mail. smtppassword );
// Email account
Mailmessage. Fields. Add ( " Http://schemas.microsoft.com/cdo/configuration/sendusername " , Strmailserverusername ); // Mail. smtpusername );
/*
* MSG. Fields. Add (" Http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout ", 60 );
* */

System. net. Mail is also easy to use.
