messaged are delivered to the envelope recipient- the argument to the RCPT TO command in the SMTP dialogue.
the "To:", "Cc:", and "Bcc:" headers within the message are almost always meaningless in terms of where a message is actually delivered to. the only time they have any effect is if you're running a command- line program like "sendmail" or "qmail-inject" with the option to scan the headers for recipient information.
I think this is qmail bug is it?
no. it is a common point of confusion for most people who don't deal with mail servers on a daily basis, but it's not a bug.
think of it like this- the "To:" header corresponds to the "To:" line at the top of a letter. if i write up a letter which says "To: Bill Gates, Microsoft" at the top, but then i place that letter inside an envelope which has your name and address on it, where is the postal service going to deliver the message? that's right- they will deliver it to you.
and when you open the letter and see "To: Bill Gates" at the top, it might confuse you at first- but then you would look at the envelope in which the letter arrived, and you would understand why the postal service placed it in your mailbox instead of sending it to microsoft.
and just as you would look at the physical envelope in which the message arrived, you can look at the SMTP envelope sender and recipient of messages which qmail-local stores in your mailbox. the envelope sender (i.e. the MAIL FROM argument) is stored in a "Return- Path" header, while the envelope recipient (i.e. the RCPT TO parameter, after any "virtualdomains" transformations) will be found in a "Delivered-To" header. in addition, qmail-scanner stores a copy of the envelope sender in the "Received" header that it creates.
