While working on an email related project, I tried using the asp.net webpage WebMail helper.
I got an error "Invalid character in header ';'" which was as a result of adding multiple recipients in my "to" string.
The documentation states
// The email address of the recipient or recipients. Separate multiple recipients
// using a semicolon (;).
So i was confused as to why it did not work.
I eventually just replaced ";" with "," in my mail list string and it worked perfect.
So is the problem from the documentation or the code.
