I have been trying to get onto these lists for a while now but I was unable to until David Wolfskill intervened and specifically allowed me in the records. Thanks David and others who replied to my earlier problems. ----- Original Message ----- From: "David Wolfskill" <david@catwhisker.org> To: "Bob @ Brisbane" <jwillson@gargoyle.apana.org.au> Sent: Monday, January 16, 2006 9:40 AM Subject: Re: Fw: Testing > On Mon, Jan 16, 2006 at 08:57:29AM +1000, Bob @ Brisbane wrote: >> Hi David >> Could we use a hammer to smash the nut and just allow the IP address for >> the time being. >> It often takes weeks before APANA gets around to fixing anything. >> My IP 203.3.126.224 is a fixed number and has been mine for some years. >> Bob Willson > > I'm (somewhat) sympathetic -- my IP address is residential DSL, but > static.

Below this is a cut and pasted earlier message from David that describes the problem I faced.

Right. And I see one message in the freebsd-test@ archive that you sent to freebsd-test without a Cc: to postmaster@ (as well). The first message I have that you sent to both was Message-Id <003801c61982$baa3aed0$0101a8c0@bob>, which hit mx1.freebsd.org at Jan 15 03:20:37 (UTC). The reason mx1 gave for declining to accept it on behalf of freebsd-test was "450 Client host rejected: cannot find your hostname". And checking: mx1(4.9-S)[8] host 203.185.225.22 Host not found. mx1(4.9-S)[9] Right. (You may be thinking that "203.185.225.22" isn't a hostname. While that is, in some senses, correct, it's not especially relevant. More below.) Here is a blurb I cobbled up a bit ago: The SMTP server in this case, mx1.freebsd.org, is set up so that it requires: * that the IP address "reverse-resolve" to a hostname and * that the hostname thus obtained resolve a set of IP addresses, one of which must match the IP address of the client and * the (fully-qualified) hostname given in the SMTP conversation (either HELO or EHLO) must resolve a set of IP addresses, one of which must match the IP address of the client. In the case in point (IP address 203.185.225.22, allocated to POWERTEL LIMITED), the first condition fails to be met. You have some options: * Use the ISP's designated mail relay host(s) (assuming, of course, that the machine(s) in question are set up to meet the above criteria). * Relay the mail off of some other machine that meets the criteria. * Finally, if neither of the above is workable, let me (postmaster@) know, and I can add that IP address to a list of "accepted" SMTP clients. Please note that this won't be very useful if the IP address assignment is dynamic. Since the mail from the Y! account worked, I don't see much point in going over it. Peace, david (current hat: postmaster@freebsd.org) -- David H. Wolfskill david@catwhisker.org It is courteous to reduce quoted text to just that needed to establish context.
