note 28080 added to ref.mail

I found that if the email address contains both user-friendly name as well as the address, like: From: Some Sender<some.sender@domain.com>\r\n the message will be delivered using mail(). In the other hand, if the address is as follows: From: some.sender@domain.com<some.sender@domain.com>\r\n the message won't be delivered. In fact, if there is an @-character in the name-part of the address, the message fails to send. I wonder what other characters may cause this? -- http://www.php.net/manual/en/ref.mail.php http://master.php.net/manage/user-notes.php?action=edit+28080 http://master.php.net/manage/user-notes.php?action=delete+28080 http://master.php.net/manage/user-notes.php?action=reject+28080
