[xmail] Re: DNSREPORT says Xmail violates RFC821 4.3 RFC2821 4.3.1
Your server is configured incorrectly. server.tab should contain the following line: HeloDomain mars.bigeagle.com.au Also the @ symbol is not legal in a fully qualified domain name.

Andreas, Cisco PIX has this behaviour when using 'fixup protocol smtp'. http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cm dref/df.htm#1067379 The fixup protocol smtp command enables the Mail Guard feature, which only lets mail servers receive the RFC 821, section 4.5.1, commands of HELO, MAIL, RCPT, DATA, RSET, NOOP, and QUIT. All other commands are translated into X's which are rejected by the internal server. This results in a message such as 500 Command unknown: 'XXX'. Incomplete commands are discarded.=20 As of PIX Firewall software Version 5.1 and higher, the fixup protocol smtp command changes the characters in the SMTP banner to asterisks except for the 2, 0, 0 characters. Carriage return (CR) and linefeed (LF) characters are ignored.

[xmail] Re: DNSReport
Actually what DOES bother me is that the server only reports the domain, not the subdomain. IE: mail.mqfloral.com claims to be host [EMAIL PROTECTED]. Where it really should be: mail.mqfloral.com claims to be host [EMAIL PROTECTED]. -Mensaje original- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] nombre de [EMAIL PROTECTED] Enviado el: Tuesday, July 22, 2003 2:08 PM Para: [EMAIL PROTECTED] Asunto: [xmail] Re: DNSReport --- Davide Libenzi [EMAIL PROTECTED] wrote: On Tue, 22 Jul 2003, Michael Lugassy wrote: Hi there, I recently ran a DNSReport on my webserver and got this.
