Subject: RCPT TO: [host>

Thank you!

No warning on [<legal.ip.address.here>]

But what if someone uses RCPT TO: <username[hostname>?

Postfix answers:

        <"<user"[host>]>: bad host/domain syntax: "[host>]"
or
        550 <<user[host>]>: Recipient address rejected: Relay access denied

Also looks little strange :-(
