Hmm, it seems you're right. It doesn't generate a bounce, but it does 550 - just too early (at the rcpt rather than data stage). Apparently it generated a bounce because I was using mail, which I guess calls exim as sendmail, rather than with smtp, so it behaves slightly differently. Here is a telnet session with the same configuration, coming from another machine: steve:~$ telnet mercury 25 Trying 216.158.52.98... Connected to mail.lobefin.net. Escape character is '^]'. 220 mail.lobefin.net ESMTP Exim 4.30 Sun, 11 Jan 2004 11:56:48 -0500 ehlo busybox 250-mail.lobefin.net Hello www.lobefin.net [216.158.52.108] 250-SIZE 52428800 250-PIPELINING 250-AUTH LOGIN PLAIN 250-STARTTLS 250 HELP mail from: [EMAIL PROTECTED] 250 OK rcpt to: [EMAIL PROTECTED] 550 unknown user And the corresponding log line: 2004-01-11 11:57:08 H=www.lobefin.net (busybox) [216.158.52.108] F=<[EMAIL PROTECTED]> rejected RCPT [EMAIL PROTECTED]: on vacation It does _not_ work as well as I had hoped, but it at least does generate a 550, rahter than a bounce.
