Some providers are picky about recipient addresses, they may refuse to send mails to an address to which mails have previously been rejected for "550 5.1.1 Bad destination mailbox address".
Sending an RCPT TO command with such an address will fail with these providers, and result in a non-standard enhanced status code. In this case, mutt only emits an error like "SMTP session failed: 550 ..." without mentioning the address associated with the failed command, which doesn't help much if there are many recipients. This patch adds extra error log about the recipient address when an RCPT TO command fails. Users then could easily distinguish the problematic recipient, and remove it or contact the provider for support.
