User writes a message, than it should be posted to 300-800 e-mails.
Firstly I-ve made message.html and mailer.php. User writes message in message.html, then clics submit, and than the script runs:
/*mailing... mailing...*/ header("Location: .........");
But, unfortunately, in this case user has to wait for long time, before he'll be redirected.
How to let user go for another location, leaving the mailing script?
