The following is the experience that I have accumulated when I wrote a message:
First, prevent formation of forms
Add in the corresponding table label
Style = "Table-Layout: fixed; Word-Break: Break-all"
Second, shield HTML code
Replace "<" and ">" in the message content into & lt; and & gt;
Third, replace hard
That is, reserves the style when signing the message writes, which also needs to be replaced.
Replace CHR (13) in ASP
Replace "/ N" in PHP
Note: If you want to combine the mask HTML code, you must replace the second point of the second point.
Everyone else has any other experience, please keep it!
