note 80332 modified in function.mail by danbrown

Apparently if using the mbstring library, and using overriden functions, the "mail" command appears to use "Content-Transfer-Encoding: BASE64" by default. Which if you combine it with PEAR Mail_Mime you'll get mails that, although they appear RFC compliant, not mailer can read correctly. To fix this it appears you should add a fixed header in the mail command (this one assumes the pear mime module is 7bit clean, perhaps 8bit would also be fine) <?php $headers['Content-Transfer-Encoding'] = '7bit'; ?> --was-- Apparently if using the mbstring library, and using overriden functions, the "mail" command appears to use "Content-Transfer-Encoding: BASE64" by default.
