I'm using a To: address in the mail() and a list of inner company
emails under the Bcc: header... but I still get the SMTP Unknown user
error... this error was not here in 4.2.3... but I can confirm that
4.3.2 does have problems with the Bcc and Cc headers... For now I guess
I will send individual emails out. :(

Some mail servers don't accept blank To, so this problem can't appear.
I'm just using Phorum and Mercury/32 mail server, then found this
problem.
X-Envelope-To header also depends on the mail server. May not be
created at all or other similar header.

When using blank "To", and only Cc or Bcc to send an email, like
below:

mail("", "the subject", 'message body',
     "From: [EMAIL PROTECTED]"
    ."Reply-To: [EMAIL PROTECTED]"
    ."BCC: [EMAIL PROTECTED]"
    ."X-Mailer: PHP/" . phpversion());

the receiver mail server will complain user unknown error, if check the
raw received mail, will like this:

......
X-Envelope-To: < [EMAIL PROTECTED]>
......
To:
......

Notice there's an extra space in X-Envelope-To header!
Anyhow, if "To" is not blank, the received X-Envelope-To is correct.
If don't leave space after the colon of Bcc and Cc, the problem could
temporarily resolved.
